Abstract
This paper proposes application of sequential function specification method to solve the inverse heat conduction problem to obtain instantaneous surface heat flux from transient temperature measurements. Transient temperature measurements beyond critical heat flux are obtained for a copper block being cooled by a liquid nitrogen spray. A method to construct the boiling curve beyond CHF is discussed. This method help in estimating the heat flux at various superheats even in the transition and film boiling region which is otherwise difficult to estimate.
