Flow Foundation (Fluids) Services

Computational Fluid Dynamics (CFD) models are built on the ability to calculate the flow with the variation in velocity and pressure throughout the fluid volume.

Foundations of Fluid Flow

CFD models have been extended over time to include more complex physics like combustion, multiphase, detailed turbulence, aeroacoustics, and coupling with other physics solvers.  These original, highly validated CFD models are still used today when the more complex models are not needed, and they can answer a significant number of fluid problems.

However, often times, it takes a skilled fluids engineer to bridge the gap between computational analysis and the environment in which real-life application is being conducted.

Consider the Pascal’s Principle, which states that when force is applied by depressing the piston in one cylinder (the input cylinder), the result is a uniform pressure that results in output in the second cylinder, pushing up a piston that raises the automobile.

The hydraulic ram, which is also employed in devices like bulldozers and the hydraulic lifts that utility workers and firefighters use to access higher places, is another illustration of a hydraulic press. The input and output cylinder properties of a hydraulic ram, however, are different from those of a vehicle jack. The input cylinder for the automobile jack is long and thin, and the output cylinder is broad and short.

This is so that the mechanic can stand comfortably underneath the automobile. A car jack’s main function is to raise a heavy object over a limited vertical range of motion.  A seasoned engineer would understand, and apply this nuance to the mathematical models.  Which is the level of expertise SimuTech Group can provide to your business.

Recent CFD Consulting Projects

 Gas Turbine Exhaust Duct

Predicted the change in turbulent pressure drop in a complex large-scale duct system preceding the gas turbines in a gas-fired power station due to the retrofitting of additional structural members. (Power Generation).

Airplane Wing

Calculated the supersonic turbulent lift and drag coefficients of various wing profiles at various angle of attacks and altitudes. Compressibility and high-speed energy effects were included as well as the accurate prediction of the turbulent shear forces and separation points. (Aerospace).

Car Body Kit

Analyzed the aerodynamic drag forces and their corresponding effect of geometry variations to the aerodynamic design of add-on car body kits for a current on-road vehicle. (Automotive).

Volatile Gas Dispersion in a Processing Plant

Simulated the transient dispersion due to an accidental release and flashing of a volatile gas in a chemical processing plant. The simulation of the gas dispersion was used to evaluate different HVAC designs. (Building Design).

Water Treatment Plant

Optimized the time that contaminants were in contact with disinfectant by calculating the turbulent mixing for several different feed streams to different configurations to different baffle and flow configurations. (Water & Waste).

Hydraulic Presses

The volume of the fluid that travels a given distance in a given amount of time remains constant as fluid passes from a bigger conduit to a narrower one. However, because the narrower pipe’s width is smaller, the fluid must flow more quickly (and under greater dynamic pressure) in order to cover the same distance in the same amount of time.
