IJREI_Numerical simulation model of solar air heater using ansys-14

Downloads: 4 Avg Rating: 0.00 By: Mr Editor Ijrei in 2017.
Thermal performance of downward- type single-pass flat plate solar air heater (SAH) with pin fins attached on absorber plate
are investigated numerically. Calculations of outlet air temperature and collector efficiency have been done with and without
application of recycling operation. Numerical simulation of solar air heater has been performed by the use of ANSYS-14
(FLUENT) software. 196 square pin fins on absorber plate has been attached and by maintaining both the pitch lengths
(transverse and longitudinal) constant optimization of fin height and thickness (side) has been done for various values mass
flow rates and results are represented in graphical as well as tabular form. The effects of in-line and staggered arrangements
of fins on the performances of solar heater have been compared. It is found that due to application of pin fins, with a mass
flow rate of 0.02 kg/s, thermal efficiency of solar air heater increases upto 99% and 91% for staggered and in-line arrangements respectively, as compared to SAH operating without fins with same air flow rate. The results showed that SAH with staggered arrangement is upto 13%, 6.5% and 4.5% more efficient than in-line arrangement with a mass flow rates 0.05, 0.01, 0.02 kg/s  respectively
