Course Learning Outcomes
Upon successful completion of ME 508, students will be able to:
- Explain the fundamental concepts of thermal radiation, including blackbody radiation, Planck's law, Stefan-Boltzmann law, and Wien's displacement law, and differentiate between various radiative properties of surfaces (emissivity, absorptivity, reflectivity, transmissivity).
- Calculate view factors for various geometries using analytical methods and apply view factor algebra (reciprocity, summation, superposition) to complex configurations.
- Implement and utilize Monte Carlo methods to determine view factors for intricate geometries where analytical solutions are impractical.
- Analyze and solve problems involving radiative exchange between gray, diffuse surfaces using the radiosity method and network analogies for enclosures.
- Extend the analysis of radiative exchange to include partially-specular and nonideal surfaces, accounting for their unique radiative characteristics.
- Derive and interpret the radiative transfer equation (RTE) for participating media, identifying the contributions of absorption, emission, and scattering.
- Apply and solve the radiative transfer equation for one-dimensional gray participating media using exact analytical techniques.
- Evaluate and implement various approximate solution methods (e.g., P-N approximation, discrete ordinates method) for the radiative transfer equation in one-dimensional participating media.
- Critically assess the assumptions and limitations of different radiative heat transfer models and solution techniques.
