HEAT TRANSFER BY CONDUCTION-CONVECTlON AROUND A HEATED THIN CYLINDER
Abstract
A laboratory made thermal probe has been tested in
conduction·convection tests. The thermal probe is made with
an inner part where the thermocouple and the heating
system are located. The rest of the probe is made with a
filling substance and an external steel cylinder. The
behaviour of the internal and external parts has been
investigated. Several thermal probes have been built in
laboratory with different filling substances and different
construction procedure. Liquids and granular incoherent
materials have been tested. Thermal conductivities have been
measured with the transient method. The convective regime
is investigated as the final steady state of the transient
temperature increase. Experiments have been performed in
liquids. Preliminary experiments have been carried out in
granular incoherent materials in order to measure the
convection heat transfer coefficient around the thermal
probe.
