Conjugate Heat Transfer Analysis for a Heat Exchanger


The Client:

A company involved into Design and Manufacturing of Heat Exchangers

Objective:

To simulate the cross flow conditions for a heat exchanger using CFD Analysis and estimate the heat transfer parameters with consideration of the tube materials.

Client Expectations:

Client expected us to simulate various heat transfer parameters using CFD Analysis for the cross flow arrangement such as heat flux, temperature distribution etc for fluid and the tube materials. The hidden expectations (client needs) were to develop an accurate CFD model for CFD Analysis, to select appropriate boundary conditions and define them in the CFD environment.

CFD Analysis Project Challenges:

Conjugate Heat Transfer refers to the combination of heat transfer in fluids and in solids. It is also known as CHT problem in the CFD Analysis jargon and considered to be a complex CFD Analysis problem to solve. Getting the input data for the CFD Analysis and setting up valid boundary conditions were the biggest challenges for this project. Our CFD experts had to refer a lot of literature available on CFD Analysis for Conjugate Heat Transfer. Our CFD analyst had to make sure to scrutinize many models to define the CFD Analysis problem properly. Our CFD consultant had to verify the results with logical reasoning by referring and comparing the CFD Analysis results to the classical Fluid Dynamics results for a simplified CFD Analysis model.

CFD Analysis Project Deliverables:

CFD Analysis results provided the requisite information such as Temperature distribution, heat flux for various cases for the cross flow heat exchanger arrangement. This helped us client to further design and estimate the capacity of the heat exchanger. CFD Analysis results were embedded in the form of a well written CFD report which included the CFD results data in the form of tables and pictures.
