Course Objectives
The purpose of this subject is to impart basic concepts pertinent to Newtonian fluid flow physics. Thereby, students will acquire and be capable to utilize this fundamental understanding for the characterization of flow domains of relevance in aerospace. In other words, with a strong background in fluid mechanics, aerodynamic optimization of flying machines can be accomplished.
Course Outcomes
CO1: Enables to distinguish fluid from solid.
CO2: Understand the stability of floating bodies based on hydrostatic force concept.
CO3: Synthesize conservation principles for mass and momentum for the description of incompressible fluid flow dynamics.
CO4: Characterize the inherent features of steady laminar incompressible flows.
CO5: Understand the concept of boundary layer – its formation, control of separation and significance in Aerospace applications.
