Empirical Formula for Instantaneous Heat Transfer Coefficient in Spark Ignition Engine 972995

A new empirical formula for instantaneous heat transfer coefficients was determined. The determination of this formula is in necessary for prediction of the instantaneous value of heat transfer coefficients to analyze in more detail the time variation of heat transfer rate from the gas to the wall in the combustion chamber of a spark ignition engine. The following formula was determined. Using this empirical formula the instantaneous heat transfer coefficients of gas in the combustion chamber of spark ignition engine was predicted and compared with experimental values.
