RECENT RESEARCH INCOMPUTATIONAL FLUID MECHANICS

2

1. To inform current research topics inthe field of Computational FluidMechanics

2.To promote research topics forUndergraduate Projects (UGP), MasterProject/Master Research or PhDresearch


OBJECTIVE

3

The systematic investigation intoand study of materials and sources inorder to establish facts and reachnew conclusions.


RESEARCH??

4

1 Graduation requirement2 Platform to demonstrate student’screativity and apply knowledge3 Contribute to new knowledge3 To disseminate knowledge4 To get money/claim (publicationincentives)5 Etc


WHY RESEARCH MATTERS

5

When considering topics for a workable research problem, askthe following questions:• Do I posses the skills necessary to complete this study?• Do I have access to the tools, lab, and equipment to

complete this project?• Do I have the time and money necessary to complete this

project?• Do I have the resources necessary to obtain sufficient data?• Do I have access to a professional in that field who will be

willing and able to advise me in the research process?


SELECTION OF RESEARCH TOPIC

6

Choose a research topic that interests you. Then……….*Find a study that has already been done and replicate itusing new definitions of some of the variables in the study(UG).

-or-*Find a study that has already been done and replicate itusing additional moderator or control variables (UG/PG(t))

-or-*Find an existing study and develop a different way to testthe hypothesis (PG(t/r))

-or-



7

*Follow an author’s suggestions for further research needed –usually found at the end of an article (PG(r))

-or-*Contact the author of an interesting study using the internetfor ideas for further study (PG(r))

-or-*Choose a problem, analyze it, and invent a completely newstudy (Ph.D)



8

• Freedom to work (FW) - The supervisor is open to ideasand is flexible about adopting alternative approaches

• Time conscious (TC) - The supervisor is consciousabout time taken for completion and is generally willingto work towards it.

• Job prospect (JP) - The supervisor’ ability to help thecandidate in obtaining a suitable job after completion ofdissertation

• Convergence of interest (CI) - The matching of interestof the student and the supervisor

• Reputation/Subject knowledge/Publications (RP) - Thereputation of the supervisor in his or her field.


CRITERIA FOR CHOOSING A SUPERVISOR

9

• Personal relationship with the professor (PR) - Cordialand understanding relationship with the supervisor

• Social networks (SN) - The supervisor’ social networkand relationship with other professors in the instituteand outside

• Number of thesis guided (TG) - Number of thesis guidedby the supervisor, the more the better

• Commitment and involvement (IN) - Supervisor’enthusiasm in guiding the thesis, emotional investment
