A method employing transient heating was developed to determine surface heat transfer coefficients associated with steam/air mixtures in batch retorts. The method was based on instantaneous introduction of a highly conductive brick‐shaped test block of uniform initial temperature into a heating medium which was prestabilized at the desired temperature and pressure conditions. The results of a study to verify the utility of the method revealed an exponential relationship between the heat transfer coefficient and the steam content of the medium.
