Conservation Principles

1. Each student can model heat transfer processes in idealized and practical systems by identifying relevant heat transfer modes and applying conservation of mass and energy.


2. Each student can describe the physical mechanisms involved in conduction heat transfer and use Fourier's law to model the conduction heat rate. Each student can apply conservation principles to develop the heat diffusion equation, apply appropriate boundary conditions, solve the heat diffusion equation for simplified scenarios (e.g. lumped/1D/2D, steady/transient, with/without generation) using analytical and/or numerical methods and apply these solutions in appropriate modeling scenarios.


3. Each student can describe the physical phenomena associated with convection, use non-dimensional parameters and empirical correlations to predict local and global convective heat transfer coefficients for laminar or turbulent flows. Each student can apply Newton's law of cooling to calculate external or internal, forced or free convection heat transfer.


4. Each student can describe the physical mechanisms involved in radiation heat transfer and apply appropriate relations to model intensity and radiative heat flux to/from a surface. Each student can determine total, hemispherical radiative properties of a surface from spectral, directional quantities and apply appropriate models to obtain the net radiative heat rate at a surface and radiative heat exchange between diffuse, gray surfaces forming an enclosure.

Problem Solving

5. Each student can identify heat transfer phenomena in real-world scenarios, use a structured method to define the scenario (e.g. 5 Ps of Problem Definition), apply conservation principles and fundamental laws with appropriate approximations to build a model that represents the scenario, solve the model using a systematic method (e.g., SAFER), and document their analysis/results using an organized structure (e.g., IMRaD) to convey conclusions and recommendations.
