The inverse heat conduction analysis of synthetical surface heat transfer coefficient during quencihign process

摘要

This paper proposes basic principles and algorithm for calculating synthetical surface heat transfer coefficient using inverse heat conduction method.Combined with developed computer programs,the calculation results have been discussed.The choice of suitable time step and space step will have great influence on calculation results.Under the condition of DT=0.01s and DX-0.001m,the curve of synthetical surface heat conduction coefficient vs.surface temeprature will be availabel accurately by multi-points method of inverse heat conductiono analysis.
