CourseDescription

Thermodynamics, fluid mechanics and heat transfer form an important branch of mechanical engineering callthermal fluid. Thermodynamics is the science of energy andof its conversion to and frommechanical energy. Itusually deals with an ensemble of macroscopic thermodynamic processes, whereas fluid mechanics and heattransferdealwiththedetailsofeachoftheseprocesses.Agoodcomprehensionofthevariousthermodynamicprocessesisessentialtothepracticeofengineering.Aquicklookaroundwillconvinceyouthattheseprocessesareomnipresentinourmodernsociety:refrigerators,thepowercycleinallsortofpowerplant,thethermalprocessespresentinaheating,ventilationandairconditioning(HVAC)systemandtheconceptofcompressibleflowbehindeveryjetengine.Thisthermodynamicscourseisthesecondoneyouwillencounterduringyourundergraduatestudyinmechanicalengineering.Thefirstcoursedealtwiththefundamentalsofthermodynamics,theproperties,states,processesandcycles encountered in engineering andwith the laws necessary to understand them.During this course,wewillbuildontheseconceptsinordertobemoredeeplyintothevariousthermodynamicprocessesandfocusonappliedsystems.MidtermwillbeheldontwolastweeksofAban.Allexamsareopenbookinwhichonlythehard‐copytextbookmaybeconsulted(withonepageofformulasornotesheet‐lettersize,bothsides).Theseexamsincludetwoparts.Thefirstpart isconceptual,consistsof shortquestions.Thesecondwhich is themainpart, studentsshouldsolve theproblemsindetail.Topicstobecoveredconsistof:
