An Experimental Investigation on the Characteristics of Turbulent Boundary Layer Flows Over a Dimpled Surface
An experimental investigation was conducted to quantify the characteristics of the turbulent boundary layer flows over a dimpled surface in comparison to those over a conventional flat plate. In addition to measuring surface pressure distributions to determine the friction factors of the test plates and to map the surface pressure inside the dimple cavity, a high-resolution digital particle ima...
متن کاملNumerical Investigation of Heat Transfer Performance of Synthetic Jet Impingement onto Dimpled/protrusioned Surface
Dynamic mesh methods and user defined functions are adopted and the shear stress transport k-ω turbulent model has been used in the numerical investigation of heat transfer performance of synthetic jet impingement onto dimple/protrusioned surface. The results show that the local time-averaged Nusselt number of the dimpled/protrusioned target surface tends to be much closer with that of flat cas...
متن کاملNumerical Investigation of the Flow Characteristics inside the Scrubber Unit
Abstract—Wet scrubbers have found widespread use in cleaning contaminated gas streams because of their ability to remove particulates and based on the applications of scrubbing of marine engine exhaust gases by spraying sea-water. In order to examine the flow characteristics inside the scrubber, the model is designated with flow properties of hot air and water sprayer. The flow dynamics of evap...
متن کاملAnalytical and Numerical Investigation of Second Grade Magnetohydrodynamics Flow over a Permeable Stretching Sheet
In this paper, the steady laminar boundary layer flow of non-Newtonian second grade conducting fluid past a permeable stretching sheet, under the influence of a uniform magnetic field is studied. Three different methods are applied for solving the problem; numerical Finite Element Method (FEM), analytical Collocation Method (CM) and 4th order Runge-Kutta numerical method. The FlexPDE software p...
متن کاملDirect numerical simulation of turbulent flow over a compliant surface
Direct numerical simulation of turbulent channel flow over a compliant surface has been performed to evaluate the friction drag reduction effect. It is found that a slight drag reduction is observed over a compliant surface. This observation indicates that drag reduction is possible using a compliant surface that is deformed passively by wall pressure fluctuation. A small wall displacement and ...
