You have just joined the design and development group at Panasonic, Inc. The first task you are given is to work on the design of a thermal system to anneal TV glass screens. Each screen is made of semi-transparent glass and weighs 10 kg. You need to heat it from a room temperature of 25°C to 1100°C, maintain it at this temperature for 15 minutes, and then cool slowly to 500°C, after which it may be cooled more rapidly to room temperature. The allowable rate of temperature change with time, ∂T/∂t, is given for heating, slow cooling, and fast cooling processes. Any energy source may be used and high production rates and uniform annealing are desired. (a) Give the sketch of a possible conceptual design for the system and of the expected temperature cycle. Briefly give reasons for your choice. (b) List the requirements and constraints in the problem. (c) Give the location and type of sensors you would use to control the system and ensure safe operation. Briefly justify your choices (d) Outline a simple mathematical model to simulate the process.
