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 In this article, different types of air-assist atomizers are introduced and air-blast, flat-fan and Effervescent atomizer models are explained. Air-Blast/Air-Assisted Atomizer Model The Fluent Air-Blast / Air-Assisted Atomizer model is a derivative of the Pressure Swirl Atomizer model. An…
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 introduces the parcel concept and its available release methods. Also, the DPM mass flow rate parameter in ANSYS Fluent is investigated via a descriptive tutorial. Parcel Concept Parcel in ANSYS Fluent software is defined as a group of monologue particles with…
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…
Grid Independence Study in DPM In numerical studies, the governing equations are discretized and rewritten in each cell. To have an exact CFD solution, we must generate an appropriate meshgrid to accurately capture variables value in each cell. The mesh…
Bosch Common Rail Injector Introduction and Purpose of the Case Study The Bosch fuel injection system delivers the metered quantity at high pressure to mix with compressed air inside the combustion chamber for efficient combustion, And The Bosch Common Rail…
In this article, we present the main steps through simulating spray modeling using DPM, in 5 steps, from general settings to post-processing and also you can see useful tips. To start with, select the Discrete phase in the Models tab of…
An Introduction to DPM Spray Literally, sprays are considered a combination of droplets immersed in a gaseous phase known as the continuous phase. They`re employed in most industries and have a wide range of applications in drying, applying chemicals, washing,…
