Further increases in efficiencies are possible by using computer simulation tools to figure out the optimum
geometry for the inlet and outlet lines. Such a simulation program was recently developed and is currently checked
for accuracy. The program is based on two finite difference schemes, a one-dimensional to predict fluid dynamic
properties inside the rotor and a two-dimensional to predict the fluid dynamic properties in the inlet and outlet
lines. Both schemes are basically solving the conservation laws for mass-(5), momentum-(6) and energy-(7) which
are (in the two-dimensional case) given by:
