Purpose – The purpose is to present a new approach for studying the phenomenon of traveling bubble cavitation. Design/methodology/approach – A flow around a rigid, 2D hydrofoil (NACA‐0012) with a smooth surface is analyzed computationally. The Rayleigh‐Plesset equation is numerically integrated...
Purpose – To address the effects of velocity profile at the discharge air grille (DAG) on the amount of entrained air into an open refrigerated display case (ORDC). Design/methodology/approach – The performance of an ORDC was studied by CFD, DPIV and LDV. The actual measured velocity profile at...
Purpose – The aim of this work consists of studying numerically the coupling between natural convection and radiation in a tall rectangular cavity by examining the effect of the emissivity of the walls, ϵ , the Rayleigh number, Ra , and the inclination of the cavity, &thetas; , on the flow...
Purpose – To conduct a numerical study on two‐dimensional, transient, buoyant flow inside an air‐filled 45°‐inclined enclosure, heated and cooled on adjacent walls. Design/methodology/approach – The governing equations obtained through the stream function‐vorticity formulation are solved using...
Purpose – The present study aims to conduct a numerical investigation of a novel film cooling scheme combining in‐hole impingement cooling and flow turbulators with traditional downstream film cooling, and was originally proposed by Pratt & Whitney Canada for high temperature gas turbine...
Purpose – To investigate the effect of aspect ratio on the quantitative analogy between developing laminar flows in orthogonally rotating straight ducts and stationary curved ducts Design/methodology/approach – A fractional step method is used to obtain the numerical solution of the governing...
Purpose – This paper aims to provide a validation of a state‐of‐the‐art methodology for computing three‐dimensional transitional flows in turbomachinery. Design/methodology/approach – The Reynolds‐averaged Navier‐Stokes equations for compressible flows are solved. Turbulence is modeled using an...
