This tutorial calculates the temperature of the shield. A jet of liquid metal at 2000 °C flows with a diameter of 4.5 mm. The jet is surrounded by a 2 mm thick radiation shield with 60 mm internal diameter.
The shield has a slit of 20° as shown in the figure. The room temperature is 30 °C. The shield absorbs heat by surface to surface radiation from the jet and dissipates it to the room by convection and surface to ambient radiation. It is desired to calculate the temperature of the shield.
In this lesson, you learn the following:
- Defining surface to surface radiation
- Defining surface to ambient radiation
- Graphing thermal results versus time
