✦ Synopsis

Letters to the E&tors the heatmg se&Ion because the presence of the hot lammar sub-layer prevents the temperature decay m the wall These results show how local values of the heat transfer coefficient can &ffer from the average values, and Illustrate the approxunate nature of the model based on the bulk mean temperature difference (0, -Bf) Equation ( 6) may be used to determme when a correctIon for end-effect error should be Included m the conventlonal method for determmmg heat transfer coefficients. Usually qm wdl be very small compared with the total heat input, but under certam condltlons (e g where b and D, are large and 8, high and where the heatmg section s very short),
