Effects of groove geometry around pin-fin perforation circumference on thermohydraulic behavior of pin-fin heat sinks under turbulent flow

The thermohydraulic performance of perforated pin-fin heat sinks (PPFHS) with different groove geometries around pin-fin perforation circumference is numerically investigated using ANSYS Fluent under turbulent flow conditions with Reynolds numbers (Re) ranging from 24,484 to 55,088. Four groove geom...
