The method was called the orthogonal simulated calculation method. The orthogonal simulated calculation was used to the combustion system of S195 swirlchamberdieselengine.
The three dimensional flow field for the bell type swirlchamberdieselengine is first calculated. The calculated results and LDV measured data are compared, which show fairly good agreement.
