CFD Analysis Shell And Tube Heat Exchanger Service

In an IC Engine, due to increase in engine temperature during operation, the NOx emission increases. Exhaust Gas Recirculation (EGR) cooler were developed to improve emission performance of the engine.

EGR Cooler is a heat exchanger that uses engine coolant (from oil cooler) to reduce exhaust gas temperature prior to recirculating them through the engine’s intake system

Problem definition 

•  The main objective is to find pressure drop and temperature rise/drop across the shell and tube sides of the cooler 

•  Effect of corrugated tubes over smooth tubes on heat transfer 

•  To simulate the flow distribution inside and identify no/low flow zone as they are the reason for hot spots 

•  Suggest design changes such as addition of baffles to increase coolant residence time and effective heat transfer 

Solution 

•  In-depth analysis and design suggestions for optimized performance
