Unsteady State Heat
Transfer Experiment
The following links contain an overview of the unsteady state heat
transfer experiment performed in the laboratory.
The objectives of this experiment were to determine the thermal
conductivity and local
heat transfer coefficients
of an aluminum rod.
The apparatus consisted of a steam jacket and an aluminum rod.
As steam passed through the jacket, thermal energy heated the rod and
created a temperature gradient.
The rod was insulated
and changes in its temperature were measured were taken over time. The data
collected was used to calculate the
thermal conductivity
of the rod.
Heat transfer behavior was studied during natural and forced convection
in order to determine the local heat transfer coefficients for the rod.
A correlation between the Nusselt number and the location of each
thermocouple was created for both natural and forced convection.
The data collected was used to calculate the local heat transfer
coefficients. The experimental
values were compared to literature values and discrepancies between the two sets
of
values were analyzed.
