The repository for the CFD Simulation case of a liquid fuel pintle-injector rocket engine conducted using the open-source CFD software, OpenFOAM.
Professor: Dr. Pavel Popov
Master's Student: Matthew Coleman
A Master's Program Thesis Project through San Diego State University
Project Start Date: 09/2020
Project Finish Date: TBD
This project uses the open-source CFD software OpenFOAM-8 in order to solve the case. This code can be found at https://github.com/OpenFOAM/OpenFOAM-8.git.
With OpenFOAM-8 installed and the repository cloned locally onto the system, there are several execuatble files to help manage the case:
Case Set-Up
makeMesh creates the mesh using blockMesh, as well as sets up the chemistry properties and merges blocks on the mesh.
Running the Case
./Allrun runs through the makeMesh executable followed by running the case using the sprayFoam solver. This version is for serial-execution.
./Allrun-background Same as Allrun except executes the solver in the background.
./Allrun-parallel Parallel-Execution for the solver.
./Allrun-FERMI_parallel Parallel-Execution for the solver on the FERMI supercomputer provided by San Diego State University.
batchScriptSmol144 The batch script used for running the parallel-execution case on FERMI.
During Execution
./followSprayLog uses tail to follow the output of the log.sprayfoam file while the solver is in the background.
./followFERMI same as above except follows the output of the FERMI node.
After Execution
./Reconstruct If ran in parallel, this command with reconstruct the decomposed mesh after the solver has finished.
Case Clean-Up
./Allclean Deletes time-stamp folders and cleans up the case for running again.
