This code is a "first cut" and is missing several friction/loss mechanisms. It also lacks a lookup table for wet steam behavior. Feel free to exercise the mode with different parameter values (for many you can just edit the '''.param''' lines) and to add improvements.

Free Piston Steam-Hydraulic Engine

Simulation using freely available LTSpice IV simulation program. LTSpice is intended for electrical schematics, so it labels everything as volts and amps. However the simulation math doesn't care whether we are voltage or pressure or mass.

This code is a "first cut" and is missing several friction/loss mechanisms. It also lacks a lookup table for wet steam behavior. Feel free to exercise the mode with different parameter values (for many you can just edit the .param lines) and to add improvements. Steam_Engine_Design/Free_Piston_Steam_Hydraulic/SpiceCode
