One interesting thing is that the output Vx and Vy matrices are of form (height*width), whereas I expected them to be (height*width*30), i. The analysis is carried out using the VoF (Volume of fluid) method which is a standard approach for the computation of multiphase systems. = Angular velocity = Angular velocity of precession. Select a Web Site. • Three measures of quality: – Skewness. We are here to help with MatLab questions or issues, not to verify your results. Boundary conditions are given in terms of Psi (stream function) where: The governing equation is: It is required to plot the streamlines (Psi = constant lines) of the flow. OpenFOAM is the free, open source CFD software released and developed primarily by OpenCFD Ltd since 2004. I'm trying to make a CFD model where I can place a source and a sink anywhere in a grid and get the fluid flow rate across each cell boundary between those locations. Simulating flow over an airfoil would not be possible with the current code. The Coriolis flow meter has many features such as direct measurement of mass flow and measurement of fluid density, which other flow meters do not support. Streamline Plots in MATLAB ®. This result agrees with computational fluid dynamic simulations. Fluid mechanics can be divided into fluid statics, fluid kinematics and fluid dynamics. The following Matlab project contains the source code and Matlab examples used for 2d lid driven cavity flow. The Cap (2P) block represents a perfectly insulated terminus for a two-phase fluid branch. It provides sophisti-cated tools to model and simulate fluid flow for complex parts and assemblies. — PDF “Simulation of Taylor-Couette flow.
