COMPUTATIONAL FLUID DYNAMICS CALCULATOR ANDROID
The Y+ Calculator is available for both iOS and Android so download your preferred version today. The Y+ Calculator app is available for both iOS (left) and Android (right). White’s Fluid Mechanics 5th edition, page 467. Its computations are based on flat-plate boundary layer theory from Frank M. The app works in either SI or Imperial units and quickly resets to sea-level conditions. at any timestep and at any location in the fluid domain. The results obtained from a CFD analysis allow you to assess pressures, velocities, temperatures etc. The Y+ Calculator computes the height of the first mesh cell given a target y+ value and the flow conditions. The use of Computational Fluid Dynamics is complementary to physical experiments and can help you in reducing the number of expensive and time-consuming prototype tests. For turbulent boundary layers, y+ should be 1. Y+ is a non-dimensional measure of wall spacing that has been normalized by wall shear stress. Use the controls to adjust the flow speed. The colors indicate the curl, or local rotational motion, of the fluid. Initially the fluid is flowing from left to right, and a linear barrier (shown in black) diverts the fluid and creates vortices. This is a simulation of a two-dimensional fluid. If you are an engineer running viscous CFD computations, setting the distance of the first grid point off the wall is essential for accurately resolving the boundary layer. Show: Tracers Flowlines Force on barriers Sensor Data. Both two-dimensional (2-D) and three-dimensional (3-D) meshes were constructed, reproducing a previously published account of a mottled sculpin.
Simply specify the flow conditions, the desired y+ value, and compute your grid spacing. This paper presents the first computational fluid dynamics (CFD)simulations of viscous flow due to a small sphere vibrating near a fish, a configuration that is frequently used for experiments on dipole source localization by the lateral line. The Y+ Calculator app is a handy and free tool for calculating the grid spacing to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations.
