Analysis of thermohydraulic efficiency increase during transformer oil flow in a minichannel with a single-row package of spherical and oval dimples at a heated wall
Annotation
Based on solving the Navier–Stokes and energy equations by a factored finite-volume method, the physical mechanism of the intensification of heat exchange in a minichannel with dimple vortex generators at the heated wall during transformer oil circulation is analyzed. It is shown that oval dimples are preferable to spherical analogs.
