Numerical investigation of the drag force reduction induced by the two-phase flow generating on the solid body surface

Wake lengths and structural responses of Korean general artificial reefs

“…It is shown from many investigators that ANSYS CFX software is fully integrated into the ANSYS Workbench environment and the reliability has been well established (Finnegan and Goggins, 2012;Gylys et al, 2012;Kim et al, 2012;Zakeri, 2009). ANSYS CFX utilizes the finite volume technique, which divides the region of interest into sub-regions and discretizes the governing equations to solve them iteratively over each sub-region; hence, the value of each variable at nodal points over the domain is approximately achieved.…”

“…(Gylys et al, 2012;van Dam, 1999;Zakeri, 2009). Accordingly, some investigators carried out numerical flow analysis of ARs to investigate the flow field characteristics around cubic and starshaped ARs (Li, et al, 2010;.…”

Peculiarities of the Leidenfrost effect application for drag force reduction

“…Our experiments [13], which were performed on the hot and cold bodies' moving in water which temperature is less than 20°C, do not show that the hot body's velocity increases by 2.5 times in comparison with the cold body [7]. Investigation showed that hot body moves in water only 1.2 times faster [11].…”

Experimental Investigation about Drag Force on the Both Icy and Non-icy Airfoils

“…This paper meant to found an improved understanding of effects of the grooved surface on the drag coefficient and the flow characteristics of cylinder. Gylys et al [2] presented an analysis of the drag force decrease through the hot spherical and cylindrical bodies movement in the water in contrast with the movement of cold bodies. Effect of 2-phase water-vapor flow on the drag force was studied both experimentally and numerically.…”
