# ***OCTOPUS***
## A repository for m5 injector design engineers to collate code performing analysis on injector flow and efficacy.
### Install with pip:
`pip install git+https://github.com/cuspaceflight/octopus.git`
### Documentation:
[Octopus Docs](https://cuspaceflight.github.io/octopus)
### Current features:
* Model flow through a simple straight orifice with a selection of 1- and 2-phase models.
* Models supported:
* Single Phase Incompressible: `python Orifice.m_dot_SPI(Pcc)`
* Homogeneous Equilibrium Model: `Orifice.m_dot_HEM(Pcc)`
* Dyer Correction Model: `Orifice.m_dot_dyer(Pcc)`
* Accurate Equations of State for multiple fluids, coefficients included for N2O.
* Example code showing some features of the `octopus` module, most documentation is in docstrings on source code.
### Currently in progress:
- [ ] Improving class heirarchy
- [ ] Adding venturi calculations
- [ ] Making nitrous data easier to access
- [ ] Improving documentation
### Eventual planned features:
* Orifice types - Waxman cavitating
* Estimation of orifice discharge coefficients (from empirical data) (?)
* Estimation of atomisation performance (from empirical data) (?)
* Determine element O/F, overall O/F
* Determine film cooling mass flow proportion (~20% is said to be sufficient to ignore the core O/F for temperature calculations, need to find the source for this - possibly NASA SP-8089)
* Warnings for combustion stability criteria (from empirical data)
