RADIATIVE OVEN
An IMMERSOL application is presented aimed at the demonstration
of the method for the 3D situation when the thermal radiation
is dominant.
A 3D oven for heat-treating samples is 0.32mx0.32m in cross
section and 1.5 m long.
A radiant heater panel consists of a row of cylindrical electrical
heating elements 1 cm in diameter, 150 cm long, spaced at a 3 cm
pitch, and backed by a wall convectively cooled from outside.
The panel has dimensions 30x150 cm and is located 30 cm above a
well insulated floor, which is also 30x150 cm. The heater elements
are rated at 5 kW each. The emittances of the elements and back wall
are 0.9 and 0.8, respectively.
Two pieces of metal and brick loads are placed on the asbestos sheets.
The heat transfer coefficient of the ceiling and back/front walls to
the ambient air of 300K are 20 and 10 W/m^2K, respectively. The heat
transfer from black side walls is rated at 300 W/m^2K.
The task is to calculate the distribution of temperatures and radiant
heat fluxes.
