HYSTERESIS OF PLANAR DOUBLE SLOT IMPINGING AIR JETS

In present study, the bistability and hysteresis of the non-isothermal flow behind two slot nozzle is numerically investigated. Theoretical review of bistability of isothermal stagnation flow is presented and both flow field patterns that exist in the region of bistability are commented on. Hysteres...
