The progress in additive manufacturing (AM) sector has transformed the ways in which heat
exchangers (HXs) can be fabricated. The complex and freeform designs which could not be …

The quest for reductions in fuel consumption and CO 2 emissions in transport has been a
powerful driving force for scientific research into methods that might underpin drag-reducing …

Transition between nucleate and film boiling potentially causes dramatic temperature
changes during fluxcontrolled operations, which may lead to catastrophic equipment …

To enhance the fin-side heat transfer capability of circle tube-fin heat exchangers, a novel fin
with ellipsoidal dimple-protrusion is introduced in this paper. The effect of the ellipsoidal …

Recently, dimpled surfaces have found great attention due to their abilities in energy
management and heat transfer enhancement, low weight, small values of pressure drop …

To provide an overview of the current state of the art of heat transfer augmentation schemes
employed for internal cooling of turbine blades and components, results from an extensive …

Turbine cooling is a battle between the desire for greater hot section component life and the
techno-economic demands of the marketplace. Surprisingly little separates the haves from …

The heat transfer coefficient between the absorber plate and air can be considerably
increased by using artificial roughness on the underside of the absorber plate of a solar air …

Experimental results, measured on and above a dimpled test surface placed on one wall of
a channel, are given for Reynolds numbers from 1250 to 61,500 and ratios of air inlet …

The use of an artificial roughness on a surface is an effective technique to enhance the rate
of heat transfer to fluid flow in the duct of a solar air heater. Number of geometries of …
