A radiation-coupled CFD study of thermo-hydraulic and 4E performance of a double-pass spiral solar air heater with progressively narrowing flow passage
A three-dimensional radiation-coupled computational fluid dynamics (CFD) investigation is conducted to evaluate the thermo-hydraulic and sustainability performance of a double-pass spiral solar air heater (DPSAH-S) featuring a logarithmic flow path with gradually decreasing passage width. The progressive reduction in...
