Computational fluid dynamics

Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial experimental validation of such software is performed using a wind tunnel with the final validation coming in full-scale testing, e.g....

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]...
