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: A review of numerical algorithms for the analysis of viscous flows with moving interfaces is presented. The review is supplemented with a discussion of methods that have been introduced in the ...

Abstract: Evaluations of loss coefficient and entrance length in the inlet region of a channel are presented. Correlations and numerical values of these quantities are provided for Reynolds number ranging ...

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: A spectral method for solving the steady flow of a shear-thinning Ellis fluid is discussed for the case of a planar channel with corrugated boundaries. Polynomial approximations are employed ...

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 ...

Abstract: An analysis of natural convection in horizontal slots has been carried out. It is demonstrated that a proper combination of heating and groove patterns can create a net horizontal fluid movement, which we refer to as the ...
