Course Description:

Review of one-dimensional compressible flow. Normal and oblique shock waves; Prandtl-Meyer flow; combined effects in one-dimensional flow; non-ideal gas effects; multi-dimensional flow; linearized flow; method of characteristics. Selected experiments in supersonic flow, convergent-divergent nozzles, hydraulic analogue and Fanno tube. Lectures: three hours per week. Laboratory: two hours per week, alternate weeks. Prerequisite: MECH 351, 361.

Course Aim:

This course is an introductory course to the subject of Gas Dynamics where the effect of compressibility on fluid flow is introduced. It starts with some basic notions of fluid flow and thermodynamics followed by one dimensional compressible flow typically in internal flow. It then treats the problem of shock waves, moving and stationary, in internal and external flow. Some methods for solving some of these flows are also presented and used in computer assignments.

Design soft skill:

Engineers often have to quantify real life problems by translating them into an engineering problem, they then have to make the appropriate assumptions then devise a solution approach using the proper tools. Therefore, the following Design soft skill will be included in this course:

Problem Analysis: An ability to identify, formulate, research and solve complex engineering problems reaching substantiated conclusions.

Practice: The sample problems are there for you to practice. Please go beyond these problems by consulting other texts and even the internet! Also, please do not rely on the solutions, try each problem on your own until you reach an impass…then try again; form study groups to discuss and work through problems with your fellow students…that’s how Engineers do it!

Evaluation: Comprehension and application of ‘problem analysis’ will be evaluated based on the Midterm and the Final Exam.

Textbook:

Please see list of suggested texts below. Sample Problems will be posted regularly on your MOODLE site

General notes:

Sample Problems will be posted on the MOODLE site for this course. They do not carry any weight in the grade, however it is imperative that you solve these problems to pass the course.

Absence : If you miss a lecture, make sure that you get informed from a friend or colleague of the material given in that lecture.

Graduate students will do a project to account for the difference in credit value between the undergraduate and graduate credit hours.

Midterm and final exam : All tests are closed book; you are allowed a standard ENCS calculator and you will be provided with the Gas Dynamics tables.

Grade review : Students wishing to review their final grade, for a valid reason, can do so in the 2nd

week of the winter term. A sign-up sheet will be posted on my door during the 1 st week of the winter term for those who wish to review their grade.
