 ## A repository for m5 injector design engineers to collate code performing analysis on injector flow and efficacy.
 
+### Current features:
+*   Choice of SPI, HEM and Dyer models returning mass flow rate
+*   Full Helmholz rho/T EOS implementation in the Fluid class for all relevant properties
+*   Orifice types - basic
+
 ### Eventual planned features:
-*   Choice of SPI, HEM and Dyer (with Solomon correction) models
-*   Compressibility corrections
-*   Orifice types - Waxman cavitating, basic
+*   Orifice types - Waxman cavitating
 *   Estimation of orifice discharge coefficients (from empirical data) (?)
 *   Estimation of atomisation performance (from empirical data) (?)
-*   Determine pressure drop, orifice mass flow, element O/F, overall O/F, etc with the above
+*   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)
 *   Document everything - kill two birds with one stone here and write up all the injector notes in preparation for the new wiki?
 
 ### Currently in progress:
-*   Finding specific enthalpy and any other important chemical properties, transport properties
-  * Possibly with multiple source data options / averaging / sense checks
-*   Decisions on classes / where everything should live
+*   Setting up class heirarchy
   * Current intended structure: Injector plate --> Manifolds --> Injector elements --> Orifices
 
 ### Things that need fixing:
-*   Sure this won't stay empty long...
+*   Not sure the HEM graph produced matches Solomon's
 
-SI base units used everywhere, except for possibly some final output and graphing.
