Mathematical Modelling of a pressure focusing Mechanism in a Heart?shaped Naturally occuring Combustor

Popis výsledku v původním jazyce

The role of pressure wave focusing in a heart-shaped reaction chamber of Brachinus (Bombardier beetle) was investigated. The defence mechanism of Brachinus was described and numerically modeled. The shape of a naturally occurring reaction chamber wasusedfor practical methane-air combustion to study the advantages of the design. Mathematical modelling of gas combustion shows pressure focusing mechanism given by the combustor shape and its important role in a gas ejection from the vessel. Numerical l calculations with stoichiometric methane-air mixture has been carried out showing different features of the design. Fully compressible laminar flow with single step kinetic mechanism was used. The ignition was set-up by rising temperature on the hot walls of the combustor. Results show, that the two phase behavior of the Brachinus defence mechanism cannot be easily reproduced with gaseous combustible mixture. The design of the chamber shows very unique flow-field and pressure wave character
