Engage CFD analysis to prevent and resolve your heat exchanger issuesComputational fluid dynamics (CFD) analysis is one of the most successful methods of solving heat exchanger problems.

HTRI e�ectively uses CFD simulation in its research and contract projects to improve heat exchanger performance for customers worldwide. CFD studies can assist in the design stage to identify potential problems, as well as resolve operational issues afterthe exchanger is in service.

HTRI’s personal approachOur researchers meticulously review your problem from every angle and utilize state-of-the-art analysis tools to

■ outline an e�cient computational modeling approach

■ define simulation boundary and initial conditions and outputs

■ generate a mesh consistent with the computational approach

■ simulate the case with appropriate software packages, including those with multiphysics capabilities

■ post-process the results and prepare a comprehensive report containing your engineering solution

We leverage our research results to expand the evaluation scope of your problem. We can quickly formulate an e�ective solution, as meshing approaches and validation cases have already been completed.

HTRI engineers and analysts are familiar with geometry and thermal-hydraulic phenomena and can rapidly apply their hands-on skills and experience to customer challenges.
