What is CFD?

When it comes to wood and steel structure design, these two trusted materials behave predictably given their static properties and simplified formulas. Determining the set of equations to calculate the loads on your building structures is an easier feat. Consequently, meeting your cost and schedule constraints for your building project would be manageable. However, such is not the case with fluid flows.

Where there’s fluid, there’s Computational Fluid Dynamics (CFD). But before CFD Analysis, enter partial differential equations (PDE) on your fluid dynamics. From gas to liquid, all your fluid flow calculations have been involved with physical laws and ruled by PDE systems initially. To put it simply, PDEs help formulate problems with multivariable functions, considering the erratic nature of fluid.

What CFD aims to provide for you now is to replace the PDE systems by transforming these laws to quantifiable solution methods. In a nutshell, Computational Fluid Dynamics (CFD) is what you will get when you intersect the three branches of fluid mechanics, computer science and physical sciences.

Using CFD, we have different sets of algebraic equations. With all these output data in place, we can now further analyze and solve your fluid dynamic equations with digital computers. In retrospect, fluid is non-linear, non-negligible and often acts in a multidimensional flow – rendering it as a challenge for any engineer to calculate as compared with fixed material properties.

This is where New York Engineers’ expertise in CFD Analysis comes in handy for your project. We combine engineering with frontier technology. Whether fluid-fluid, fluid-solid, or fluid-gas interaction, our proficient engineers are fully equipped with the knowledge and tools to visualize the flow velocity, density, temperature, chemical concentrations, and thermal impact of fluid flows on all mediums.

Fluid in Motion

Learn the ins-and-outs of how fluid flow works so you can better bridge the gap between cognizance and misconception. At NY Engineers, we partake on educating our clients, colleagues and industry specialists on our caliber so all parties can get a grip on how CFD Analysis can bring value to your engineering project.

In fluid dynamics, all fluid flows are subjected to unbalanced forces, resulting in continuous motion. These could range from liquids to gases, such as:

• meteorological events (rain, wind, hurricane, flood)
• environmental threats (air pollution)
• automobile combustion
• heat exchangers
• heating, ventilation and air-conditioning (HVAC)

On top of real experiments, you have computer simulations when you utilize CFD Analysis for your project. Here in NY Engineers, we stack up all fluid flows against their macroscopic properties of density, viscosity, pressure, temperature and velocity. From there, our expert engineers group the fluid flows into these classifications:

• viscous / inviscid
• compressible / incompressible
• laminar / turbulent
• single-phase / multi-phase

Why is there a need for classification? Our experienced engineers have put their time-tested knowledge to good use and proved that the reliability of such CFD simulations will greatly depend on such disparity. This will lead to better predictions and performance optimization when our engineers perform CFD Analysis on your engineering design projects.

Why Use CFD Analysis for Your Future Projects

CFD Analysis is right on top of our arsenal for top-tiered engineering services, and rightfully so, for several reasons. Here in NY Engineers, we transform your complex problems to simple. Conventional methods or experimental techniques are often difficult to discern, but vis-à-vis CFD Analysis, our engineers can make your life easier by providing enhanced insights on the fluid flow patterns.

To better facilitate your understanding, we provide you a quick comparison on Experiments vs. Simulations:

• Experiments
• Quantitative description using measurements
• One quantity at a single time
• Limited range of operating conditions
• Measurement errors
• Simulations
• Quantitative prediction using CFD software
• Several desired quantities in high-resolution time and space
• Virtually all realistic operating conditions
• Modeling and iteration errors

In totality, both techniques have their own pros and cons, but in relation to efficiency, CFD Simulations fare better than the former solution despite the iterative processes required. All the more that you can save up on your valuable resources such as time and money, which could prove to be beneficial whatever your involvement as a stakeholder in the project life cycle. This translates to cheaper, faster and multipurpose operations for you – leading to your reduced development costs, higher bottom line and business valuations.

How CFD Design Cycle Works

At NY Engineers, we are fully capable of producing comprehensive design iteration process to render you accurate results on CFD Analysis. However advanced the simulation technology may be, keep in mind that CFD Simulations are never 100% reliable, on the account of:

• Miscalculated input data founded on baseless assumptions
• Inaccuracy due to limited computing power

Case in point, this is when a professional engineering expertise could prove to be indispensable for you, and New York Engineers fit in the bill excellently. Our specialty in CFD Analysis lies in the three phases from pre-processing to solving, and down to post-processing. When we analyze the interfacing matrix of CFD, all these input and output data calculated by a computer hardware can never be produced without a baseline data acquisition from a human being.

1. Pre-processing

Enter New York Engineers, where we initially state the problem to be solved. From here on out, we construe mathematical models and methods through our in-depth scientific knowledge on fluid dynamics. Next, we form assumptions on the fluid flow to be modelled, and transform core concepts to discretized computer model with mesh generation.

1. Solving

Actual computations on discrete function values are performed by the iterative solver in this phase, where multiple solvers can range and vary according to efficiency and capability in solving physical phenomena. Implementation and debugging are performed on the CFD software, while simultaneously conducting the simulation run based on design parameters and criteria.

1. Post-processing

For the final phase, CFD simulation results are visualized and analyzed by our expert engineers. Here’s where NY Engineers can provide intrinsic value for you: our highly experienced team are armed with an arsenal of engineering prowess, mathematical ability and attention to detail. We verify and we draw conclusions based from the calculated results, all while partnering with industry-specific specialists for an interdisciplinary approach. We validate, we adjust, and we iterate. At NY Engineers, we do not stop until we get the desired and accurate results. This is your leverage.

To simplify the concepts for you, these are the main components of CFD design cycle, where countless iteration process from multidisciplinary collaborators can take place:

• Analysts or engineers for initial problem statement
• Mathematical models and methods transformed from scientific knowledge
• Software coded with algorithms for CFD Analysis
• Hardware for actual calculation performance
• Professional engineers for interpretation of CFD simulation results

Where You Can Apply CFD Analysis

Complicated at first from a technical perspective, but when deduced down to comprehensive tidbits, CFD Analysis prove to be useful in almost any, if not all, industries. The wide range and extent of Computational Fluid Analysis (CFD) goes so far from energy and power generation, down to product design and MEPF services.

Some particular applications where numerical simulations of fluid flow can be useful include:

• Architectural design for comfortable living environments
• Weapon development and damage estimation in military groups
• Optimization of oil recovery strategies in petroleum engineering
• Aerodynamic shape design for airplanes and automotive vehicles
• Meteorological forecast for weather and natural disasters
• Computational hemodynamics for curing medical arterial diseases
