Wave Rotor Topping Cycles
for Gas Turbine Engines
System Design Performance Calculation
Multi-port wave rotors are modeled using macroscopic mass and
energy balances, one-dimensional gasdynamic wave timing, and
sub-models for entropy produced in viscous, passage gradual opening
and closing, blade blockage, and incidence-induced losses. The model
provides on-design wave rotor performance estimates, port timing, and
machine size with efficiency amenable to parametric analyses. The
modeling approach identifies important wave rotor variables and
allows incremental loss levels to be estimated. The model has been
validated through comparison with numerical calculations and divider
cycle experimental data. The model is extremely fast, requiring only
milliseconds of CPU time on a PC, which makes it ideal for
preliminary design.
