ES 202 Fluid and Thermal Systems Lecture 1 (12/02/2002)

Road Map of Lecture 1 Introduction Administrative announcements Review of ES 201 concepts pertinent to this course

Introduction Something about myself Something about yourself

My Place of Birth Also known as “The Pearl of the Orient”

My Undergraduate School You should be familiar with this place!

My Graduate School Anyone from California??

My Doctoral Research Understand how noise is generated in supersonic engine exhaust M = 1.2 M = 0 Sound wave Turbulence Shock wave

Something about Yourself Name What do you prefer to be called? Major Hometown Think of a recent fluid mechanical/thermodynamical experience to share with us Fill out questionnaire

Outline of ES 202 Apply conservation and accounting principles to thermal and fluid systems Fluid systems include  Hydrostatics  Pipe flow (internal flow)  Lift and drag (external flow) Thermal systems include  Pure substance  Ideal gas  Steady state devices  Cycle analysis

Course Composition Textbook: Fundamentals of Thermal-Fluid Sciences (Cengel & Turner) Class web page: 30 lectures 10 homework sets (numbered according to week number) 3 laboratory sessions 3 lab write-ups 2 exams and 1 final

Homework Policy Encourage group discussion BUT write-up must be individually done ABSOLUTELY no copying of homework!! Grading based on solution procedure Due by 5 pm every Monday at my office (not my mailbox), 20% grade reduction per day afterward In case of difficulties, consult with instructor in advance

Laboratory Related Announcements Location Formation of lab group Pre-lab for Lab #1 Lab write-up is due one week after lab session at my office by 5 pm

General Classroom Rules Mutual respect (golden rule) Punctuality  Minimal disturbance to fellow students and teacher  Turn off your cell phone  No chewing tobacco Questions are encouraged No question is stupid Your question is valuable to others in learning

My Preference Learning happens both inside and outside the classroom –Inside classroom: interactive, participation –Outside classroom: office hours, review sessions Welcome feedback anytime during the quarter (class format/materials/pace) Open door policy: you are welcome to come to my office (O-219) individually or in group My is My home phone number is You may phone me before 10 pm.

From Your Memory Bank Tell me your honest to heart comments of ES 201? Name as much as you can recall from ES 201.

From My Understanding ES 201 –bird’s eye view of major concepts in engineering analyses –Starts from the general principles then refines to specific areas in later courses

Familiar Terminology Close system/open system Control mass/control volume Storage Production Net influx Conservation of mass Conservation of linear momentum Zeroth law of thermodynamics First law of thermodynamics Second law of thermodynamics Entropy
