Steady state temp. distribution

Click For Summary

Discussion Overview

The discussion revolves around a 2D heat conduction problem, specifically focusing on the steady state temperature distribution and the associated boundary conditions. Participants explore the dimensionality of the problem and the formulation of temperature as a function of spatial variables.

Discussion Character

  • Homework-related
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant expresses uncertainty about the problem, indicating they could not attempt a solution due to a lack of understanding of certain parts.
  • Another participant questions the assumption that the problem is 2D, prompting a discussion about the dimensionality of the heat flow.
  • A suggestion is made to define the temperature variable as a function of x, proposing a transformation to eliminate non-homogeneity in the equation.
  • One participant argues that the heat flow appears to be 1D, suggesting that temperature should be expressed as T = T(x).
  • Concerns are raised about the upper and lower boundary conditions, with specific values and derivatives mentioned for clarity.
  • A mathematical expression for temperature is proposed, questioning whether it satisfies all boundary conditions.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the dimensionality of the problem or the appropriate formulation of the temperature distribution. Multiple competing views remain regarding the nature of the heat flow and the boundary conditions.

Contextual Notes

There are unresolved assumptions regarding the dimensionality of the problem and the implications of boundary conditions on the proposed solutions. The discussion reflects varying interpretations of the problem setup.

Homework Equations


ıt is nonhomog type ,2D heat conduction problem

The Attempt at a Solution


I don't understant To parts so I couldn't attemp a solution.
 
Physics news on Phys.org
What makes you think it is a 2D problem?
 
Shouldn't we found T(x,y)
and for upper and lower parts should I write as afuction of x To(x) and then define new temperature variable Q=T-To to eliminate nonhomog on the left side
 
From the figure, it looks to me like the heat flow is 1D from the left side to the right side. T = T(x).
 
What about the upper and lower boundaries?
Bc should be x=0 t=to
X=b/2 t=to
Y=0 dt/dy =0
Y=b t= to(x)
 
Does the following satisfy all the boundary conditions: ##T=T_0\left(1-\frac{x}{a}\right)##?
