A heat exchanger design & manufacturer in United States wanted find out the root cause of a field failure. They wanted to evaluate the heat transfer rate, flow distribution and solid particle sedimentation from multiphase flow in the heat exchanger.
We studied different inlet flow rates and selected an optimum flow rate to prevent solid sedimentation. We finalized the process with optimum velocity to achieve desired heat transfer rate.
It was difficult to accomplish the same study with an experimental set-up because the operation time of a heat exchanger in measured in hours making it impossible to visualize solid sedimentation in tubes.
The CFD simulation done by our team made it possible to visualize solid sedimentation and the solve sedimentation issue in few days’ time without further trial & error approach on the installed site.
Our simulation study reduced problem resolution time from months to a few days.
