Mechanical and Energy Engineering Ph.D. Courses You Could Take

Advanced Heat and Mass Transfer (3 hrs)
Fundamental conservation equations are established in the beginning. Based on the fundamental equations, students learn laminar velocity and temperature fields, laminar boundary layer, turbulent flows, natural convection and mass transfer. As a case study, heat and mass transfer issues in chemical vapor deposition are discussed.
Multiphase Transport Phenomena (3 hrs)
Fundamentals of transport phenomena in multiphase systems including boiling, evaporation, melting and solidification, sublimation and vapor deposition, condensation, two-phase flow, and interfacial sold-liquid-vapor phenomena. Starting with the governing equations with localized and averaging formulations and also including discussions of applications to energy systems, electronic cooling and material processing.
Theory of Elasticity (3 hrs)
Analysis of stress and strain in two- and three-dimensions, equilibrium and compatibility equations, and strain energy methods; torsion of noncircular sections, flexure, and axisymmetric problems. Topics include kinematics, balance laws, constitutive equations, nonlinear elasticity, classical small-deformation theory, formulation and solution of boundary-value problems of linear elastostatics.
Impact Mechanics of Materials (3 hrs)
Stress wave generation, propagation and interaction with interfaces; uniaxial stress and uniaxial strain waves; formulation and derivation of 1-D stress wave equations in solids; experimental methods for high-rate material behavior characterization; split Hopkinson (Kolsky) bars; dynamic fracture and fragmentation of brittle materials.
Energy Harvesting Technologies and System Design (3 hrs)
Energy harvesting is the conversion of ambient energy present in the environment into electrical energy. Energy harvesting system has a wide range of applications, including energy efficiency enhancement for a system, embedded power source for wireless sensor networks, embedded power for biomedical devices. Introduces the design of energy conversion and storage systems from mechanical energy. Major topics include: vibration energy harvesting using piezoelectric materials, vibration energy harvesting using electromagnetic technique, thermoelectric energy harvesting, energy harvesting circuits, storage of harvested energy and selected applications of energy harvesting systems.
