6. Specific goals for the course

a. The student will…

  • Adopt a systematic problem solving approach, consistently and effectively.
  • Diagram heat flows for conductive, convective, and radiative processes.
  • Find and use material property values.
  • Convert and use appropriate units of energy, power, flux, etc.
  • Write conservation equations for planar, cylindrical and spherical systems.
  • Apply assumptions such as steady state, number of dimensions, order of magnitude, and/or constant properties to simplify conservation equations.
  • Solve the energy conservation equation for the temperature distribution using appropriate boundary and/or initial conditions.
  • Calculate heat fluxes into and out of a control volume.
  • Draw resistance circuits and calculate the overall heat transfer coefficient, U, for compound systems.
  • Calculate the temperature distribution, heat flux, efficiency, and effectiveness of extended surfaces such as fins.
  • Use lumped capacitance and exact solution models to solve transient heat transfer problems.
  • Calculate transport dimensionless numbers and explain what they represent.
  • Use fluid velocity profiles to calculate boundary layer shapes and thicknesses.
  • Calculate convection heat transfer coefficient, h, for external and internal flows using formulas and graphs of experimental results.
  • Explain the causes and relative magnitudes of free convection.
  • Calculate free convection coefficients using equations and experimental results.
  • Label key regimes and heat transfer features of boiling and condensation curves.
  • Compare and contrast parallel, cross, and countercurrent flow in heat exchangers.
  • Determine the needed surface areas and/or fluid flow rates for heat exchangers given unit operation or process energy needs.
  • Calculate and explain heat exchanger efficiency.
  • Predict likelihood and account for consequences of fouling.
  • Define radiation terminology such as blackbody, grey surface, emissivity, etc.
  • Relate surface temperature to radiation wavelength and energy.
  • Calculate the view factor between two surfaces and use it to calculate heat transfer.
  • Write and solve the mass and molar forms of the 1-D mass conservation equations.
  • Calculate absolute and relative species velocities and fluxes.
  • Use heat transfer relationships and analogous equations to solve diffusion and advection mass transfer problems.
  • Predict which kind(s) of heat transfer will be relevant for a given situation.
  • Describe implications of problem solutions and perform additional “what if” calculations to understand patterns in the “bigger picture”.
