Thermodynamics I
3 Credits
A basic course introducing the classical theory of thermodynamics. Applications of the first law of thermodynamics are used to introduce the student to thermodynamic processes for closed and open systems. The Clausius and Kelvin-Planck statements of the second law are then correlated with the concept of entropy and enthalpy to investigate both real and reversible processes and the thermodynamic properties of pure substances. These techniques are then used to evaluate thermodynamic cycles for a variety of applications in power generation and refrigeration. Students are then introduced to techniques to improve thermal efficiency of these cycles such as reheat, regeneration, and co-generation.
MECE-210
Fluid Mechanics I
3 Credits
This course investigates the physical characteristics of a fluid: density, stress, pressure, viscosity, temperature, vapor pressure, compressibility. Descriptions of flows include Lagrangian and Eulerian; stream-lines, path-lines and streak-lines. Classification of flows include fluid statics, hydrostatic pressure at a point, pressure field in a static fluid, manometry, forces on submerged surfaces, buoyancy, standard and adiabatic atmospheres. Flow fields and fundamental laws are investigated including systems and control volumes, Reynolds Transport theorem, integral control volume analysis of basic equations for stationary and moving control volumes. Inviscid Bernoulli and the Engineering Bernoulli equation are utilized when analyzing fluid systems. Other concepts studied include incompressible flow in pipes; laminar and turbulent flows, separation phenomenon, dimensional analysis.
MECE-211
Engineering Measurements Lab
2 Credits
This course is focused on developing skills and knowledge in the areas of instrumentation, computer data acquisition (DAQ), measurement theory, uncertainty analysis, data analysis, and technical report writing. Specific topics that are covered include:
• Physical dimension variability assessment
• Centrifugal pump performance evaluation
• Temperature, pressure, and flow instrumentation and measurements
• LabVIEW programming and DAQ hardware application
• Transient measurements including computer data acquisition
• Digital signal input and output
Each topic includes background theoretical content with some individual exercises and then a team-based lab with accompanying lab report. Reports are submitted first in draft form and are reviewed by peers in class before preparing them for final draft submission
MECE-310
Heat Transfer I
3 Credits
A first course in the fundamentals of heat transfer by conduction, convection and radiation, together with applications to typical engineering systems. Topics include one- and two-dimensional steady state and transient heat conduction, radiation exchange between black and gray surfaces, correlation equations for laminar/turbulent internal and external convection, and an introduction to heat exchangers analysis and design by LMTD and NTU methods.
