General forms of turbulence models are outlined along with their defects and palliatives for
these in relation to turbomachinery. The turbulence modelling hierarchy available in …

Artificial roughness applied on the absorber plate is the most acclaimed method to improve
thermal performance of solar air heaters at the cost of low to moderate friction penalty …

In this study, the heat transfer and friction characteristics of four different rib geometries-45°
angled, V-shaped, W-shaped and M-shaped ribs in a two-pass stationary channel have …

Accurate prediction of ribbed duct flow and heat transfer is of importance to the gas turbine
industry. In the present work, a computer code has been developed to study the turbulent …

A novel solar cavity receiver was proposed in Part 1 to facilitate operation at ultra-high
temperatures (> 1300 K). The concept featured enclosing a directly irradiated liquid metal …

This paper introduces a phase one computational design analysis study of a hydrokinetic
horizontal parallel stream direct-drive (no gear box) counter-rotating Darrieus turbine …

Fogging is an effective cooling system used for gas turbine (GT) inlet air cooling. In this
study, three fogging strategies were tested: direct fogging, fogging with a natural gas (NG) …

The flow in the suction chamber of an external gearpump is numerically analysed. The
evolution of the boundaries of the domain is very complex, and an arbitrary Lagrangian …
