Computational Fluid Dynamics (CFD)
CFD is a powerful engineering tool that can be used to investigate complex fluid flows around heat exchange equipment. Studies can analyse heat exchanger geometry for vibration, maldistribution and bypass issues.
Through CFD services, we can achieve routes to heat exchange solutions with better and quicker clarity. With the power of CFD, proposed solutions can also be simulated to give the peace of mind of engineers when making critical project decisions.
Harnessing the power of CFD
CFD is a computer model of fluid flow that uses a program to solve the Navier-Stokes equations. This is done by using CAD to draw the geometry from which a mesh of the fluid volume is produced. The mesh is made up of many thousands or even millions of individual elements.
For each element, the program solves the Navier-Stokes equations based on the information for adjacent elements. The program iterates through this process until it converges on a result. CFD can also be used to investigate complex fluid flows inside tube using non-Newtonian fluids or high viscosity fluids.
A considerable amount of information can be obtained from the results, and this includes velocity and temperature profiles to vector plots and more detailed numerical results. This is ideal for example when investigating a heat exchanger geometry for areas of high velocity that may cause vibrations or areas of maldistribution.
