This slide is describing how to set up the OpenFOAM simulations including rotating geometries.
The SRF (Single Rotating Frame) is covered and MRF (Multiple Reference Frame).will be covered in it.
Setting and Usage of OpenFOAM multiphase solver (S-CLSVOF)takuyayamamoto1800
?
The S-CLSVOF solver in OpenFOAM uses a coupled volume of fluid (VOF) and level set method to simulate multiphase flows. It uses a level set function to track the interface and reinitialize it, improving on the standard VOF method. The solver has been implemented in OpenFOAM versions 2.0.x and higher but boundary conditions for the level set function have not been fully developed. The document provides information on setting up and running a dam break tutorial case using the S-CLSVOF solver by modifying an existing interFoam case.

This document discusses two methods for obtaining contour surface positions from OpenFOAM simulations: 1) Using the OpenFOAM sample utility which extracts contour data along surfaces defined in a sampleDict file, and 2) Using Paraview to visualize and export contour data to CSV files. The sample utility creates surface data folders containing sampled contour positions, while Paraview allows contour visualization and automated output of positions over multiple time steps.
Estimation of numerical schemes in heat convection by OpenFOAMtakuyayamamoto1800
?
The document discusses numerical schemes for estimating heat convection in computational fluid dynamics, highlighting key challenges such as conservativeness, boundedness, and transportiveness when solving diffusion-convection equations. It emphasizes the importance of carefully monitoring the cell Peclet number to prevent issues like overshoot and undershoot, especially in scenarios with high Prandtl and Schmidt numbers. The recommendation is to utilize stabilized numerical methods for resolving complex problems effectively.
Spatial Interpolation Schemes in OpenFOAMFumiya Nozaki
?
The document discusses spatial interpolation schemes in OpenFOAM. It begins by explaining how spatial derivative terms in the finite volume method (FVM) are discretized by integrating over cell volumes and surfaces. It then describes how values at face centers are obtained by interpolating from cell center values using algebraic relationships and weighting factors. Common interpolation schemes in OpenFOAM include upwind, linearUpwind, linear, and limitedLinear. The specification of interpolation schemes on a term-by-term basis is demonstrated. Code examples show how schemes such as upwind, linearUpwind and midPoint calculate interpolated face values and weighting factors differently.
This slide is a trail CHT analysis for relatively complex bodies with chtMultiRegionFoam which is an solver of OpenFOAM. Two methods to make mesh are explained.
