#12steps Video Tutorial - Conjugate Heat Transfer on Ansys Fluent

on

 This is the first episode of 12 steps video's tutorials. I hope You like it :) 

First U need to know what is Conjugate Heat Transfer. 

Conjugate heat transfer is a type of heat transfer analysis that involves both solids and fluids. It takes into account the effects of conduction in solids and convection in fluids, as well as the interactions between them at the interface. Conjugate heat transfer is important for many engineering applications, such as cooling of electronic devices, heat exchangers, combustion chambers, and solar collectors. ¹²


Some examples of conjugate heat transfer problems are:


- A heat sink that dissipates heat from a power supply unit by increasing the surface area in contact with the air flow generated by a fan. ²

- A shell-and-tube heat exchanger that transfers heat between two fluids separated by a thin metal wall. ²

- A nuclear reactor core that transfers heat from the fuel rods to the coolant fluid. ⁴

To solve conjugate heat transfer problems, one needs to use a numerical method that can handle both solid and fluid domains, as well as the coupling conditions at the interface. Some of the methods are:

- The domain decomposition method, which divides the problem into subdomains and solves them separately, then matches the solutions at the interface. ¹

- The finite element method, which discretizes the problem into elements and applies variational principles to obtain a system of equations. ²

- The finite volume method, which discretizes the problem into control volumes and applies conservation laws to obtain a system of equations. ³⁴

Quick Tip: How to fix Error: GENERAL-CAR-CDR in Ansys (Fluent)

 The error message Error: GENERAL-CAR-CDR: invalid argument [1]: improper list means that there is a problem with the scheme code or the UDF (user-defined function) in your case or data file . Some possible solutions are: Save the case and data file and try to reopen it. Reset the Fluent Setup tab and try opening the mesh. Remesh the geometry and reopen in Fluent. Change the material definition from “Solid” to “Fluid” in Design Modeler. Change the transient to steady if you are using evaporation-condensation as the phase interaction mechanism. Check the syntax of your UDF and make sure it follows the new rules in Fluent 6.2.16 or later. I hope this helps you resolve the error. If you need more assistance, please visit the Ansys Learning Forum or contact Ansys Support .

How to define porosity (porous medium) in Ansys CFD (Fluent, CFX)

 To model porosity in ANSYS Fluent , you need to define the porous zone and the porous media properties in the setup. You can follow these steps: In the Fluent interface, go to the Cell Zone Conditions panel and select the zone that you want to make porous. Check the Porous Zone option and click Edit. In the Porous Zone panel, you can choose between two methods to specify the porous media resistance: the Superficial Velocity method or the Physical Velocity method. The Superficial Velocity method uses the superficial velocity (the velocity of the fluid if there were no porosity) to calculate the pressure drop across the porous zone. The Physical Velocity method uses the physical velocity (the velocity of the fluid inside the pores) to calculate the pressure drop across the porous zone. You can also choose between isotropic or anisotropic porosity, depending on whether the porosity is uniform or varies in different directions. Depending on the method and the type of porosity you choose,

How to... fix "gui-domain-label: no domain selected" in Ansys Fluent and MEMERR in CFX

In today's post, we will deal with another error that may occur during the analysis. The error that is described below concerns Fluent and the wrong definition of user monitors that are displayed during simulation. These can be monitors concerning the average velocity in the domain volume, the values of the maximum temperatures of the solid domains, the average values of the heat transfer coefficient from the defined planes of the model, etc. Generally speaking, today's entry is about how to correctly define monitors and how to transfer them between subsequent analyzes.
