Introduction This article discusses DPM boundary conditions, including reflect, trap, escape, wall-jet and wall-film. Discrete phase boundary condition In discrete phase simulations, the interaction between particles and walls is essential to significantly predict a particle’s fate because wall impingement may…
Introduction To DPM Physical Models In this article, we aim to investigate all DPM physical models provided in ANSYS Fluent. Physical Models Particle Radiation Interaction The radiation effects must be considered in cases where a high temperature dominates the fluid…
Introduction In this article, we investigate the motion of a particle from its injection to its final probable destination. Particle Motion In a separate article, the trajectory calculations were discussed briefly. The governing equation on the discrete phase in general…
Introduction This article discusses all drag law models provided in ANSYS Fluent software. There are 14 models available. It has been tried to investigate the most applicable models. Drag Law Models Totally, there are fourteen drag law models available in…
Introduction This section will investigate the evaporation process modeling in Ansys Fluent software. Two main methods will be discussed separately. Droplet evaporation & Multi-component evaporation. Droplet Evaporation The evaporation process should be studied from two different aspects; Heat transfer and…
Introduction This article investigates the general settings of any DPM simulation located in the Discrete Phase Model dialog box, including interaction, particle tracking and particle treatment. Interaction The following figure shows that the first window consists of three main…
DPM Abstract In this article, We overview the concept of the discrete phase model, assumptions, governing equations, and some limitations of the model. Overview of DPM In fact, any flow consisting of two or more phases is called multiphase. From…
