tubes with various spherical dimple configurations. A numerical analysis, supported by …

This paper introduces a comprehensive study on the hydrothermal and entropy generation
performance of convergent tubes designed with different dimple shapes. The effects of the …

Enhancement of heat transfer in solar air heater systems using corrugations has the dual
benefit of enhanced heat transfer area and enhanced flow turbulence. This work presents …

An inverse optimization is performed for the shape (profile) of a rib-element that is located
within a rectangular flow-channel. The optimization is useful to improve not only heat …

The modern gas turbines need to run at very high inlet temperature to promote their power
output. Thus, improvements in cooling technologies play a significant role for enhancing the …
