Heat radiation between two non-parallel surfaces

AI Thread Summary
To calculate heat radiation between non-parallel or non-perpendicular surfaces, view factors are essential but often limited to specific angles. A formula for determining view factors for angles between 0-180 degrees is sought, as existing resources primarily cover parallel and perpendicular cases. The discussion references a link to a thermal radiation table that may provide useful data. Participants emphasize the importance of understanding geometric relationships in radiation heat transfer. Accurate calculations are crucial for effective thermal management in engineering applications.

Hi everybody,

How do you find the heat radiation between two surfaces that aren’t perfectly parallel or perpendicular to each other?

I know that the view factors play a part, however, I can only dig up view factors for parallel and perpendicular surfaces:

Is there a formula for finding the view factor and thus the radiation between surfaces between 0-180 degrees?

Many thanks,

Tina

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...
