This paper presents results of numerical
investigation, based on two-dimensional model, of a
wave disk micro-engine concept taking into account full
set of unsteady, centrifugal, Corriolis forces existing in
such configuration. Even in two-dimensional
simplification, the engine model derived guarantees
conservation of mass flow through the simulated
combustion chamber. A series of different geometrical
configurations is analyzed. Investigation concentrates on
the pure unsteady wave engine configuration. The waveengine
design investigation presented in recent paper
focused on two main problems: realization of gas
compression and simultaneously a torque generation.
Compression performance has been confirmed in almost
any considered configuration but the torque generation
was much below the expectations. Results of numerical
simulations are presented in form of pressure,
temperature and velocity distributions as well torque
variations.
