Next Limit xFlow 2015

Introduction The Challenge of Traditional CFD In the traditional mesh-based approach, the reliability highly depends on the quality of  the mesh, and engineers spend most of the time working on the discretization. Furthermore, there are severe difficulties in dealing with the changes in the topology of the domain for problems involving the presence of moving parts or fluid-structure  interaction. Why is XFlow so different to the current CFD solutions? Simple – particle-based approach that avoid the traditional meshing process  XFlow is a next generation CFD software system that uses a proprietary state-of-the-art Lattice Boltzmann technology, and is specifically designed...

Solving a Gasoline Direct Injection Engine Simulation

A three dimensional single cylinder CFD simulation, of a 4-stroke spray guided Gasoline Direct Injection(GDI) Spark Ignition (SI) engine, is performed in this tutorial. Detailed boundary conditions are shown in Figure 4.1: Problem Schematic (p. 173). Engine simulation is started from Intake valve opening (IVO) and fuel is injected during the intake stroke. Homogeneous fuel air mixture is compressed and spark ignited 15° before compression Top Dead Center (TDC).[1] [1] Download Tutorial Coming Soon …. —————————————————— [1]...
