4 Teaching style This course teaching mainly depends on classroom lecture. Besides the textbook teaching, it also includes the teachers' latest scientific research works and achievements show, and combines with an assignment, class discussions and laboratory facilities visit. 1 Normal lecture 2 Classroom exercise and discussion Students learning style Combining with the latest scientific progress, the course is intended to perform a class teaching. At the same time, each student is regularly required to write a research report and make a presentation according to the teaching content and related literatures reading. Classroom practice In this course, laboratory precision experiment instruments and large facilities can be available to demonstrate for students. By use of this teaching program, students can master some usual methods about gas, liquid and solid multiphase flow calculation theory and simulation calculation, and their scientific research skills and engineering practice abilities can be improved. Experiment (computer or assignment) training content In this course, students are required to complete a set of typical gas solid or gas liquid multiphase flow industrial system (such as cyclone separator, pneumatic conveying system, pulverized coal concentration device and burner, boiling system with vapor liquid two phase flow, liquid fuel atomization, etc.) scheme design and its animation demonstration. In the process of conducting this task, students should refer to the relevant literatures and technical standards, and use multiphase flow theory and method. The task mainly includes the numerical optimization for main components of gas solid/gas liquid multiphase flow, a scheme design according to the optimized parameters, and a three-dimensional drawing design. Finally students need to carry on the product animation demo. Method of Assessment: Course activities are weighted in the following way: 1 Class attendance 15% 2 Individual assignments 55% 3 Class presentation 30% Class attendance Attendance of students in class includes performance, discussion, in-class exercises and presentation. Individual assignment Each student needs to complete an assignment independently after classroom teaching.

5 Class presentation Each student is arranged to make a presentation independently at the late stage of teaching. Reference books: 6. Textbook: Guo LieJin.
