Advanced Thermal and Fluid Engineering Assignment -

Instruction - Develop CFD programs to solve simple problems in this project. There are two parts in this project.

Part one: Simple initial value problem

Assignment - Please read the attached problem description before doing the assignment.

(1) Find out the equation of motion of the cylinder. The derivation procedure of the equation must be included in the report.

(2) Develop a numerical method for predicting the vibration of the cylinder. The procedure of deriving the FDM formula must be included in the report.

(3) Develop a MATLAB program for solving the problem. The MATLAB program code must be included in the report.

(4) Keeping the damping coefficient of c = 100 N·m/s, conduct numerical simulations for KC=2 to 20 with an interval of 2 and find out the variation of the power with the KC number.

(5) Keeping the KC number to be constant of KC=10, conduct numerical simulations for c=0 to 2000 N·m/s with an interval of 50 and find the variation of the power with c.

(6) In the report, show the time histories of the vibration for all the calculated cases.

(7) Discuss how KC and c affects the power generation.

Part two: One-dimensional convection diffusion problem

Assignment - Please read the attached problem description before doing the assignment.

(1) Develop a finite difference method (FDM) formula for solving the equation. The procedure of deriving the FDM formula must be included in the report.

(2) Develop a MATLAB program and use this program to do the simulation and answer the following questions. Divide the soil depth into 200 cells when solving the problem numerically. You must attach the MATLAB program in your report.

(3) If α = 0.0002 m2/s, find out when the temperature at the depth of 1.5 m reaches 25oC.

(4) If the temperature at the depth of 1.5 m reaches 25oC is defined as T1.5, do the simulations for α in the range of 0.0002 m2/s to 0.001 m2/s with an interval of 0.0001 m2/s and discuss how α on T1.5 and why.

There are two parts in this project, each student needs to complete the work assigned in each part and submit a written report. The report must be in the format of Miscrosft Word file and submitted through vUWS. Reports in hard copy will not be accepted. Students will develop CFD programs to solve simple problems in this project. Submitting the report late due to your own internet connection problem will be treated as late submission without a valid reason. To avoid delay, you need to submit the report well before the due date.
