Fluids mechanics deals with the Navier-Stokes equations and in this blog, we will discuss the beauty of these equations that describe fluid flow and how fluid mechanics impact our everyday world. Fluid mechanics has a historical legacy that goes back to Prandtl’s original ideas of simple control volume theory. It was built around rigorous physical…

Drag in Aerospace Vehicles
During design, development, and performance evaluation of an aerospace vehicle, vehicle drag is estimated to : determine flight characteristics, such as range, endurance, maneuverability. Propulsion system sizing. Effect of payload/carriage of aircraft performance. The design life-cycle majorly consists of three phases,(i) conceptual, (ii) preliminary, and (iii)critical design phases.
Aerodynamic Flows : Classification
In the aerodynamic study, the vehicle is subjected to several types of flows. The major flow classification are as follows: Continuum and Non-Continuum flows Steady and Unsteady flows Uniform and Non-uniform flows Incompressible and compressible flows Inviscid and Viscous flows Laminar and Turbulent flows Mach No. flow regimes (a) Very-low speed Subsonic (b) Subsonic (c)…
PhD Journey : Blog #2
Wed 28 July 2o21 0800 am In research, writing is an integral part of the research. Prof Alan Macfarlane, the author of almost 20 books, guided more than 400 researchers, explains beautifully, saying that ‘Stop Thinking, Start Writing’. He explains how we have to think like a painter, making rough sketches of our thoughts without…
