Purpose
To numerically model forced convection heat transfer over arrays of solder balls.
Design/methodology/approach
The characteristic based split (CBS) scheme has been used to solve the incompressible Navier‐Stokes equations on unstructured meshes.
Findings
The results show an increase in heat transport with increase in Reynolds numbers. A significant change in heat transfer is also noticed with change in angle of attack.
Originality/value
The presented results will be useful in designing cooling systems for electronic components.
