Objective of Primer:
The objective of this primer is to provide a brief overview of the interface of inverse
heat transfer wizard.
Purpose of heat transfer wizard:
The purpose of this wizard is to determine the heat transfer coefficients as a function of
surface temperature and location of the given part from the known thermal history. Heat
transfer coefficients are the necessary thermal boundary conditions that are required to
accurately model a quenching or heating process.
Methodology:
A generic heat treat geometry which is representative of a family of parts would be
selected. This part would be instrumented with several thermocouples near the surface of
the part as well as the inside of the part. The instrumented part would then be subjected to
the quenching process. The time versus temperature data for all the thermocouple
locations would be collected. Based on an initial guess of heat transfer coefficients,
DEFORM would run an initial thermal simulation of the quench process. DEFORM
optimization routines would then compare the simulated time-temperature modeling
results with the experimental data and would modify the heat transfer coefficients until a
good agreement between the simulation and the experimental data is reached.
