The main focus will be showing the derivation of the fundamental models relating rate of conservation of heat, mass, and/or momentum to temperature, composition, and pressure by using: Rate equations, thermal resistance networks, heat transfer coefficients from correlations, flow rates and pressure drops in internal flow configurations using mechanical energy balance (namely Bernoulli equation), Steady-state and transient heat transfer in one dimension, reductions of full conservation equations to approximate forms and finally black body radiation exchange. The second aim is to apply more advenced modeling techniques to derive and obtain solutions from conservation principles, making appropriate connections between equations/calculations and physical phenomena Derivation of conservation laws (energy equation, Fick’s 2nd Law, Navier-Stokes equations) using control volume analysis, calculation of Newtonian and non-Newtonian flow fields. Comparison between integral analysis and scaling analysis.

Identify and describe mechanisms of heat transport phenomena present in given processes. conduction, convection, radiation and nanofluidics. For the fluid mechanics: Newtonian and non-Newtonian flows, Forced and natural convection. Flow in circular and slit channels.

1. Develop a basic knowledge of the physical principles that govern the transport of momentum, energy, and mass, with an emphasis on the mathematical formulation of conservation principles.
2. Explain the basic convection equations that describe heat, momentum and mass transfer at steady-state, develop modeling thinking and learn to determine the initial and boundary conditions in the basic transport equations
3. Develop the ability to transform practical problems into mathematical equations and to analyze a given set of equations analytically or numerically
4. Develops the ability to identify and solve problems related to flow across a flat surface and to identify and solve simple equilibrium flow states, simple cases of heat transfer at steady state by conductive and convection
5. Apply the knowledge gained from the course to the solution of materials engineering problems involving transport phenomena.
