Two-Dimension Steady-State Conduction

  1. 1. Two-Dimensional Steady-State Conduction<br />The following images represent the solutions to a series of two-dimensional heat transfer calculations. The images are accompanied by a collection of supporting animations.<br />The animations and images supplement the class interactions and discussions on heat transfer.<br />The images and animations were intended to support the students understanding of the governing equations and also the meaning of various concepts.<br />The animations are available to view at http://www.youtube.com/user/MBRBLU. <br />Suggestions for use<br />The images (and animations) can be displayed and students asked to describe what they see, in relation to<br />the boundary conditions<br />the likely energy balance<br />They might also be asked to describe<br />the relationship between the isotherms and streamlines of heat flux.<br />the relationship between the isotherms and the various boundary conditions<br />Alternatively, the students could be presented with a description of the boundary conditions only and asked, for each case, <br />to plot the likely temperature distribution across the slab (including isotherms)<br />to plot the lines of heat flux<br />The boundary conditions for the cases are shown in table 1 below.<br />Table 1.
