Heat transfer between two cylinders

AI Thread Summary
The discussion centers on heat transfer between two concentric cylinders, with the inner cylinder at 200°C and the outer cylinder featuring a large cutout. The primary modes of heat transfer identified are convection and radiation, while the role of conduction through the base plate is questioned. Participants suggest that analytical solutions may not be feasible for this scenario, recommending finite element analysis as a more effective approach. The inquiry aims to understand the temperature rise on the inner surface of the outer cylinder and the ambient temperature increase due to heat transfer. The context relates to practical applications in vulcanization molds, emphasizing the complexity of heat transfer dynamics in such systems.

Imagine two cylinders in which one cylinder in within another.(Please refer attachment)

The annular space between the two cylinders is filled with air.

The outer cylinder is provided with a substantially large cut out

The inner cylinder is maintained at a temperature say 200 deg c

I know that for the inner cylinder,the convection and radiation will be the modes of heat transfer.

My question is how can i find the temperature rise of inner surface of outer cylinder.

Also how to find the increase in ambient temperature due to the convection and radiation from the cut out.

This is to improve my conceptual understanding.Actually this kind of heat transfer happens in vulcanization moulds.

Is my question unclear ?
 
Why do you neglect the transfer through conduction? I mean, through that base plate.
Just curious.
I don't think you can find some analytical solution for this. You can use finite element analysis.
 

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
