# heat transfer

## Looking for an open PhD position

Hello and good day,

I have completed my Master in Mechanical Eng. (GPA 3.58) from the University of Malay (QS Ranking 114), Malaysia. I have published over 18 ISI articles about convective heat transfer, Turbulent flow and Eco-friendly synthesis of nanofluids in high impact factor journals. I aim to focus on any of the following areas:

## ASME 2015 IMECE Abstract Deadline 11:59pm March 9

As the largest interdisciplinary collaboration for mechanical engineering, you need to present your research at IMECE.Submit an abstract to present your paper to more than 4,000 attendees from 75+ countries representing more than 20 mechanical engineering disciplines. Include your research in this cross-disciplinary mix to help shape the technical content of the meeting and actively participate in the dialogue.

Dear users,

## How to find the average temperature a surface? ABAQUS -Heat transfer -user subroutine

Choose a channel featured in the header of iMechanica:

I want to model a concrete slab with a void inside the concrete. It is a thermal analyse where I apply a heat flux to the bottom surface. Within the void heat is transferred by radiation and convection. For simulating heat convection within the void, I use the surface film condition function in interaction module. I have to define the film coefficient and sink temperature. I decided to use the average temperature of the void surface for sink temperature. I don’t know how to define the average surface temperature. I think I have to use Abaqus Subroutine.

## Applying heat flux for a specific amount of time using ANSYS

Hi everyone,

how can I apply a 'X' amount of heat flus for a specific amount of time? It'll be helpful to include the steps especially for the part on specifying the amount of injection time (say 3 micro seconds)

Thanks!!

## Modeling heat transfer involving a phase change (ice to water) using Abaqus

I'm modeling the transient heat transfer of a cooler with an ice pack in it. How does one accurately model the phase change of the water? Here's what I've tried so far:

1. Added latent heat property to material card. Used Latent heat = 334 kJ/kg, Solidus Temp = 0, Liquidus Temp = 0

Result: Error, Solidus and Liquidus temps cannot be equal

2. Solidus temp = -0.01, Liquidus temp = 0.01

Result: Analysis ran, but diverged very early in the analysis.

## partition at Abaqus standard at input file

Dear Abaqus Users;

## material deposition to substrate simulation at ABAQUS

Hi;

I am trying to simulate material deposition to substrate. In our case material is added to substrate  and there is a distributed heat flux with constant velocity acting by node by node. I want to simulate showing the added material in the simulation and its effects. There is a command for that called Model Change in the ABAQUS. So is someone familiar to that kind of problem. And also I need to account mass diffusivity while the material is melting.

I will be gratefull for any advice you can spare

Best Thanks

## Thermal resistance

How can i prove that the thermal resistance in a sphere ( Biot number >> 1 ) mainly determans the speed of the heat transfer. Hope somebody can help me with this problem
