If it is not constant, how to calculate it analytically? Is there any other relation to calculate Q

We know that, Conduction Heat Transfer Q = KA(t2-t1)/thickness K is the coefficient of thermal conductivity. If T2 = 1020°C and T1= 22°C also consider we know A and thickness value. K depends on temperature. K varies with temperature. For all the materials we have a tabular data of K for...

Q1 = (-K*A1*(1020-T))/d1 Q2 = (-K*A2*(T-20))/d2

The temperature T1 at the top Surface is 1020°C and T2 at the Bottom Surface is 20°C and K is the thermal conductivity of the material. What is the conduction heat Transfer Q. ?

The geomentry consists of two parts in complete contact with each other. The first part is a Stadium shape with 5 mm thickness and a height of 39.4mm. The second part is also Stadium shape with 0.9mm thickness and a height of 64.8mm. The Bottom of the first part is at 1020°C and the top for...

How to modify this Formula? and arrive at the solution. Q = -K(Th-Tc)A/thickness

So can I proceed by adding the intensity contribution from multiple sources? In the example I quoted in the previous Reply, the intensity at Point 1 is the sum of 46,25 and 12 i.e. 83. Not just 46. Is there any kind of basic physics behind this addition of intensity. So that I could study more...

This is how I stared the Problem. I took the flat Surface on the left side and placed 20 Points on ist Surface. Also I took the top curved Surface and placed 20 Points on it. I calculated the angle of incidence for all the considered Points on the Surface. I already took into account the...

The heat Sources can be moved (Maximum distance between the wall and the heat source is 80mm). I ran the calculations in MATLAB by varaying the distance between the Radiators and the muffle. The heat source is a cylinder of 19mm Diameter. The whole set up is completely insulated and there is...

Yes that is the usual approach. But due to some constraints I have to stick with this. The intensity of the heat flux from the Sources varies with the angle of incidence. To my understanding and knowledge if a Point on the work volume if getting heat flux from 2 sources, say A and B. Say the...

Sorry that I did not mention that. I am trying to move the heating Elements around the "Muffle chamber"(Yes it is a furnace in a Simulator used to heat the specimen) so that I get the same intensity of Radiation at all Points on the muffle chamber. GOAL : To achieve same intensity on all...

The intensity is proportional to the square of the distance between the source and the body and also depends on the angle of incident. I = The intensity at 0° (Assuming I = some constant) then I0 = I cos(Theta) Theta = the angle of incidence. I want to solve this using trignomentry. Is it...

Thank you :)

I have two bodies, one at a higher temperature say 1000°C (Body A) and the other is at 22°C (Body B). Body A emits Radiation (Surface to Surface interaction). The temperature of Body A is maintained by a constant supply of Energy. The Body B will absorb the Radiation Energy from Body A, and its...
