Fig. 17From: Geometric effects in the design of catalytic converters in car exhaust pipesCase (i): Time evolution of the fraction of unburnt gas using a cosinusoidal arc. Solutions are numbered according to time: the blue curve is the initial state, the black one is the final one, at time T=1; z(L,T) is the fraction of unburnt gas injected into the atmosphereBack to article page
