Cell-Set Modelling for a Microtab Implementation on a DU91W(2)250 Airfoil
(MDPI, 2020-12-20)
Microtabs (MTs) are a regularly used flow control device in terms of wind turbine optimization. The present study introduces the application of the novel cell-set model for an MT implementation on a DU91W(2)250 airfoil. ...
Experimental Air Impingement Crossflow Comparison and Theoretical Application to Photovoltaic Efficiency Improvement
(MDPI, 2020-07-10)
The photovoltaic cell temperature is a key factor in solar energy harvesting. Solar radiation raises temperature on the cell, lowering its peak efficiency. Air jet impingement is a high heat transfer rate system and has ...
