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.

Discuss the processes for manufacturing components of complicated shapes in larger quantities.

Starting with a spring index of C = 10, design a compression coil spring of 302 stainless wire with squared ends. The spring is to deflect y = 50 mm, for an applied force of F = 90 N and to close solid when ys = 60 mm. At closure, use a design factor of 1.2 guarding against yielding. Select the smallest diameter wire where wire diameters are available in 0.2-mm increments between 0.2 to 3.2 mm. For the design, specify the wire diameter, the inside and outside diameters of the coil, the spring rate, the total number of coils, the free length of the spring, the final factor of safety, and stability conditions.

Hello! I have some questions related to using Ansys Fluent, I have read the instruction of Ansys Book , but I still do not understand clearly, can you help me? They are as the following:
1. When do we need to use pressure inlet for B.C for the inlet boundary and pressure outlet B.C for the outlet boundary?

2. Can we use pressure inlet B.C for the inlet boundary and outlet B.C for the outlet boundary in one fluid flow study (air flow, gas flow..)? The reason why I ask this question because I used to see on the internet written that if we use pressure inlet B.C for the inlet boundary, we are not recommended to use pressure outlet B.C for the outlet boundary, we are recommended to use velocity outlet B.C for the outlet boundary. Is it right or not?

3. Does the operating pressure in the operating condition effect the gauge pressure in the pressure outlet/ inlet ?

4. In the wall B.C, what does it mean if I choose the stationary wall or the moving wall? Sorry, I have read the instruction of ansys, but I still do not get it.

Thank you in advance! I will thumb you up!

What methods can be used in gearwheel production without chip removal?

At the beginning of the compression process of an air standard Otto cycle, p1 = 1 bar, T1 = 300 K. The maximum temperature in the cycle is 2250 K and the compression ratio is 9.8. The engine has 4 cylinders and an engine displacement of Vd = 2.7 L. Determine per cylinder: a) the volume at state 1. b) the air mass per cycle. c) the heat addition per cycle, in kJ. d) the heat rejection per cycle, in kJ. e) the net work per cycle, in kJ. f) the thermal efficiency. g) the mean effective pressure, in bar. h) Develop a full exergy accounting per cycle, in kJ. Let T0 = 300 K, p0 = 1 bar. i) Devise and evaluate the exergetic efficiency for the cycle.
