I am presently involved in CFD research and Development work for 3 years. My basic qualification is BSc Mechanical Engineering. Then I did MSc Engineering. I also did a 6 Month Post graduate Diploma in CFD from Beijing University of Aeronautics and Astronautics. Now my employer wants me to do further studies in CFD. The nature of my commitment is such that my employer can not spare me for long time. The only option left is to register in some advanced application oriented course based on Home Assignments.

Any suggestion in this regard would be of great help to me.

are you using a specific code (commercial etc) if so then most commercial code vendors provide training courses in the use of their code. if the code is a widely used NASA (or perhaps) DoD code like CFL3D then they might offer courses. from time to time universities offer short courses in various aspects of CFD and other things that nearby professionals can come in and take. these aren't exactly what you want but they are short (usually < 2 weeks).
