The one and half
months CFD internship program at CCTech is divided into three
modules:
-
Training on
CFD fundamentals
-
Training on
CFD software packages
-
Project work
with industrial exposure
There will be
daily two hours lecture from CCTech faculty members and working
professionals. The reaming time, student will spend working on
individual seminars and projects assigned to them.
Following is the
outline of topics covered in training sessions
