CFD Analysis of Combined Serial Two Shell Pass Shell and Tube Heat Exchanger with Continuous Helical Baffles
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 6
Abstract
In the present era where energy demands are growing everyday it has become very important to capture every available energy from the hot source and utilize it for the process with minimum wastage. With this view, the combined serial two shell pass shell and tube heat exchanger (CSTSP) concept had been put forward and simulated using Fluent. Though the novel model of the heat exchanger has a higher heat transfer rate than the conventionally used segmental baffle heat exchanger but it poses a limitation with a higher pressure drop. This paper analyses the CSTSP model by incorporating certain changes in the geometry to try out two test cases namely CSTSP-B & CSTSP-C. Numerical analysis is performed on these models and their performance is compared with the original model. This study aims to put forward more insight on the performance of the CSTSP model heat exchanger to help researchers in future to optimize the geometric model and obtain a balance between heat transfer and pressure drop.
