| contents | Impact of wind velocity and angle of attack on restricting input heat flow for solar‐assisted thermoelectric power generator with plate heat sink with cylindrical fins Prateek D. Roul Subhankar Ray Manmatha K. Roul Sudhansu S. Sahoo Swarup K. Mahapatra Prasanta K. Satapathy Environmental Progress & Sustainable Energy Abstract This study aims to ascertain the effects of wind speed and the angle of attack of the heat sink on the value of limiting input heat flow in solar‐aided thermoelectric generators (TEGs). This work primarily looks at the limiting input heat flow for TEGs with a 150°C allowable hot side temperature. The fin sink configuration involves the selection of a fin block with twelve 100 mm‐long cylindrical fins. A computational fluid dynamics (CFD) model that has been validated against published experimental data is built and analyzed in this work using numerical techniques. Four TEGs are contained within a finned base plate and a target block in the CFD model. The air movement within the wind tunnel replicates the wind outside. Focused solar heat flow is directed toward the target block's face. The findings show that when ambient wind speed increases from 1 to 5 m/s at a 0° angle of attack, the maximum limiting heat flux for the TEG increases from 26,700 to 42,780 W/m 2 , preserving the permissible temperature of 150 ± 0.5°C on the hot side of the TEG. The highest limiting heat flux for a 45° AOA and a 5 m/s wind speed is found to be 42,500 W/m 2 . Additionally, it is noted that at a 45° AOA, a change in wind speed from 1 to 5 m/s results in a 55.68% variation in the maximum input heat flux. 10.1002/ep.70430 http://onlinelibrary.wiley.com/termsAndConditions#vor |
