Conjugate heat transfer simulation of sulfuric acid condensation in a large two-stroke marine engine - the effect of thermal initial condition

In the present study, conjugate heat transfer (CHT) calculations are applied in a computational fluid dynamics (CFD) simulation to simultaneously solve in-cylinder gas phase and temperature field within liner of engine. The effects different initial temperatures with linear profiles across investigated on wall as well sulfuric acid formation condensation. temporal spatial behavior condensation suggests importance CHT under large two-stroke marine engine relevant conditions. Comparing mean value through inner outer sides liner, an difference 15 K profile is appropriate condition initiate liner. Moreover, effect amount water vapor air studied. current results show that more sensitive variation than
