Response Surface Methodology Type: Genetic Aggregation Model The genetic aggregation model as an response surface methodology type solves an iterative genetic algorithm. It aims to find the best response level for each output variable or parameter. This method selects the…
DOE Models: Introducing Box-Behnken Design or BBD The Bancon Box Design (BBD) model as a DOE model has three levels for dividing design points related to input parameters or factors. Three levels include -1, 0, +1, where levels +1 and…
Central Composite Design(CCD) As mentioned in previous blog, CCD is one of the DOE method. This blog aims to explain this model. The Central Composite Design (CCD) model has five levels for dividing different modes of input factors or parameters.…
Optimization with Machine Learning: What is Machine Learning? Machine learning (you can use for optimization purposes) is an application of artificial intelligence (AI) that allows systems to learn and improve from experience without being explicitly programmed automatically. Machine learning focuses…
Reference Values In this article, you will find formulas for several important Dimensionless numbers (Lift, Drag, Pressure, pitching moment, and Convective Heat Transfer coefficient ), Friction drag, Reynolds number, Nusselt number, and then the applications of reference value in ANSYS…
This blog describes the type of pressure like stagnation or total, atmospheric, gauge, and operating pressures. Then we bring the equations of these pressures. Finally, we have thoroughly explained these pressures in ANSYS Fluent software. Stagnation pressure We know that…
In this blog, we describe Solver Task Page in ANSYS Fluent software. We explain the Type (Pressure and Density Based, and related algorithms), Velocity Formulation (Absolute, Relative), and Time (Steady and Transient). To enter this section, follow the path below:…
In this blog, we first explain the Navier-Stokes equations and definition of CFD, then the steps of solving a problem by computational fluid dynamics by ANSYS Fluent software (Pre-Processing, processing, and post-processing). Navier-Stokes equations The final form of Navier Stocks…
Introduction The dimensionless variable Y-plus represents the distance from the wall to the first grid cell's center, also, Y-plus is a distance with no dimensions. In other words, Y-plus renders the vertical space between the element's center and the wall…
What is Meshing in ANSYS? grid means converting the computational domain to smaller subdomains to solve momentum, turbulence, and energy equations and finally obtain results for all levels of the simulated model. Introduction It is critical to creating a high-quality…
Optimization process(DOE & RSM) in ANSYS- in Simple Words This article will discuss the optimization process and explain the related terminologies such as DOE & RSM, CCD, etc. Using an example, we will further introduce the mentioned methods and options.…
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…
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…
Introduction In many industrial applications, the injected droplets don`t remain constant in shape and distortion occurs due to body forces and hydraulic instability. Thus, a breakup breaks the parent droplets into smaller children. The most well-known application is in sprays…
Introduction This article introduces discrete phase model (DPM) laws, particle types and available injection types. It has been tried to explain the most applicable injection types in detail. DPM Laws There are five particle types available in ANSYS Fluent software.…
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…
Introduction In this article, different types of atomizers are introduced. Also, Plain-Orifice and Pressure Swirl atomizer models are discussed. Type of Atomizers ANSYS FLUENT offers sophisticated injection types for sprays that describe breakup phenomena. For most injections, you must provide the particles'…
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…
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,…
