V_dV(theta)

A thin wrapper around Cython code for pickling purposes

V_shell(theta)

Vdisp()

Returns displacement of compressor in m\(^3\)/revolution

ambient_heat_transfer()

The ambient heat transfer for the compressor in kW

Returns a positive value if heat is added to the compressor

Mathematical Analysis:

\[x = {L_c}\cos \theta + \sqrt {L_1^2 - L_c^2{{\left( {\sin \theta } \right)}^2}}\]

\[\dot x = - {L_c}\sin \theta \dot \theta + \frac{{ - L_c^2\sin 2\theta }}{{2\sqrt {L_1^2 - L_c^2{{\left( {\sin \theta } \right)}^2}} }}\dot \theta\]

\[\bar \dot x = - \frac{{\dot \theta }}{\pi }\int_0^\pi {\left[ { - {L_c}\sin \theta + \frac{{ - L_c^2\sin 2\theta }}{{2\sqrt {L_1^2 - L_c^2{{\left( {\sin \theta } \right)}^2}} }}} \right]d\theta }\]

\[\bar \dot x = - \frac{{\dot \theta }}{\pi }\left[ {{L_c}\cos \theta } \right]_0^\pi = - \frac{{{L_c}\dot \theta }}{\pi }( - 1 - 1) = \frac{{2{L_c}\dot \theta }}{\pi }\]
