This course deals with the experimental techniques in Fluid Mechanics. One part of the course focuses on different techniques and challenges associated with the measurement of flow features. Other part of the course has emphasis on the statistical analysis of experimental data. Thus, this course would provide an understanding on several experimental methods in Fluid Mechanics and would unveil hypotheses concerning with the cause-and-effect relationships. It represents the most valid approach to the solution of theoretical advancement in the field.

Intended audience: Undergraduate students of Mechanical/Chemical/Aerospace engg. (5th semester onwards) and postgraduate students specializing in the thermofluids/Fluid Mechanics/Aerospace/Automobiles; industry personnel associated with Fluid Machinery/automobile and aerospace engineering; faculty members associated with Mechanical/Chemical/Aerospace engg.

Prerequisites: Basic UG-level Fluid Mechanics and Thermodynamics
