Abstract: The performance of grooves capable of reducing shear drag in laminar channel flow driven by a pressure gradient has been analyzed numerically. Only grooves with shapes that are easy to manufacture have been considered. ...

Abstract: Heat transfer resulting from the natural convection in a fluid layer contained in an infinite horizontal slot bounded by solid walls and subject to a spatially periodic heating at the lower wall has been investigated. The ...

Abstract: Propulsion generated by wall vibrations in the form of traveling waves was investigated. A model problem consisting of two parallel plates free to move with respect to each other was used. Vibration of one of these plates ...

Abstract: Drag reduction in turbulent channel flows has significant practical relevance for energy savings. Various methods have been proposed to reduce turbulent skin friction, including microscale surface modifications such as ...
