Abstract

The Low Pressure spray Breakup (LPB) model of Papageorgakis and Assanis has been implemented in the multi-dimensional code KIVA-3V as an alternative to the standard Taylor Analogy Breakup (TAB) model. Comparison of spray predictions with measurements shows that the LPB model, in conjunction with the standard k-ε turbulence model, has the potential for simulating the evolution of hollow cone sprays with acceptable fidelity, both from qualitative and quantitative standpoints. After validating the LPB model, illustrative studies of mixture stratification are conducted for a Direct Injection Gasoline (DIG) combustion chamber resembling the Mitsubishi design. The effects of reverse tumble strength and injection timing on mixture quality in the vicinity of the spark plug are explored. Overall, the study demonstrates how the KIVA-3V code with the LPB model can contribute to the optimization and control of mixing in DIG engines. [S0742-4795(00)00303-3]
