Numerical analysis of absorber tube of solar parabolic trough collector with and without insertion by using Ansys Fluent
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 12
Abstract
In this work, Computational Fluid Dynamics analysis has been conducted for the fluid flow in absorber tube of a parabolic trough collector with and without insertions. This project aims to improve the efficiency of the heat transfer rate from the absorber tube wall to the working fluid by using various types of inserts and internal fins. Some of the methods of increasing the efficiency of the heat transfer rate to the working fluid are: - (1) increasing the contact area of fluid with absorber tube, (2) using some obstacles such as insertion which increases the residual time of fluid and thus reducing pressure across the tube, (3) decreasing the velocity of the working fluid. The analysis has been carried out to study the effect of heat transfer in absorber tubes with various types of insertion profile and also to compare the results with absorber tube without insertion.
