The intention of this course is to build on the previously gained foundations in thermodynamics, fluid dynamics and heat transfer introduced in the 1st Professional year courses. This course develops the students’ analytical engineering skill set using specific and more advanced applications of thermodynamic and thermal systems. The students will gain the ability to investigate, assess, analyse and design thermal systems including: power generation, a variety of energy conversion cycles, refrigeration, heating, cooling, heat exchange, insulation and heat transfer. This course will allow students to apply and practice the systematic methodology required to tackle the types of applied thermal engineering and related design problems that they might typically encounter in their graduate mechanical engineering careers. The material covered is core knowledge for mechanical engineers, and leads into final year elective options in energy engineering. Course Delivery and Learning Activities: Students will study assigned readings in the required text attend lectures, and work through example problems. Assessment of mastery is based on a 3-hr final examination of all topics worth 40% of course total marks. Homework exercises are assigned and marked, tutorial exercises of numerical modeling investigations are marked, and regular quizzes give feedback to students on their learning progress.
On successful completion of this course students will be able to:ANALYSE AND DESIGN THERMODYNAMIC CYCLESApply thermal science methodology to systems with multiple components and carry out simultaneous solutions of energy balance on components, retrieve data and interpret results Apply 2nd Law concepts of entropy balance in steady flow energy conversion processesApply knowledge of 1st and 2nd Laws to analyse thermodynamic cycles including: Otto, Diesel, Brayton, Rankine and vapour-compression cyclesAssess cycle efficiencies using 1st and 2nd Laws applied to Control VolumesAnalyse thermal, 2nd Law and conversion efficiencies and explain parameter changes that improve efficiencyApply Dalton’s Law of Mixtures to moist air and understand use of the psychrometric chart as related to HVAC, drying and cooling tower applicationsUNDERSTAND AND MODEL HEAT TRANSFER PROCESSEDApply thermal energy conservation laws to evaluate energy flows involving conduction, convection and radiation heat transfer processesFormulate heat transfer problems such as: 1-D and multidimensional conduction, extended surface heat transfer, internal and external flow, transient heating and cooling, and radiation exchangeDesign basic heating, cooling, heat exchange, and insulation systemsAssess forced and free convection problems using analytical and empirical correlationsAnalyse thermal radiation heat transfer by evaluating view factors, emissive and absorptive power, and multi body exchangeNUMERICAL MODELLINGUse an industry-standard numerical modeling tool, Engineering Equation Solver (EES), to carry out parametric studies of thermodynamics and heat transfer systems
