Heat flux Engineering Analysis Toolkit

HEAT

Description:

The Heat flux Engineering Analysis Toolkit (HEAT) is a suite of tools for predicting the heat flux incident upon PFCs in tokamaks, and the associated temperature distribution throughout the PFCs.
The toolkit connects CAD, FVM, MHD, Plasma Physics, Visualization, HPC, and more, in one streamlined package.
The objective is to enable engineers and physicists to quickly ascertain heat loads given specific magnetic configurations and geometric configurations.

In its current form, HEAT can predict 3D heat loads from 2D plasmas for limited and diverted discharges.
It can calculate time varying heat loads and temperature profiles. HEAT can also be used to perform field line traces. In the coming year, the following modules are scheduled to be added to HEAT: -Gyro orbit effects -3D plasmas -Radiated power (detachment) scenarios -ELMs

There were three objectives taken into consideration when designing HEAT:

1. pre-shot estimation of heat loads
2. post-shot confirmation of heat loads and associated physics models
3. design optimization

The first HEAT paper is currently under review in the journal Fusion Science and Technology, and will be published under open access.
A link will be provided when the paper is published.

An appImage is now available so that users can run HEAT on a linux machine with a single file. appImage is available under 'releases' and has been tested on Ubuntu18.04, Ubuntu20.04, Centos7, Centos8. The appImage release is still in beta version, so there are likely still bugs. Bugs can be submitted to this github repo.

The author engineer is Tom Looby, a PhD candidate for Oak Ridge National Lab. This project is openSource under the MIT license.

Examples:

Below are a few examples of HEAT output. HEAT produces time varying 3D heat fluxes, and can easily create visualizations leveraging the power of ParaVIEW. There is also a HEAT presentation from Aug 2020 available here.
