Question 1) Computational fluid dynamics (CD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows.

CD typically deals with numerical solutions of differential equations governing the transport of mass, momentum, and energy in moving fluids. CD has become an indispensable tool for many engineers. Even though the impetus to its development was initially provided by some sections within the aeronautics and aerospace industry, it has grown to become an essential tool in a range of other design-intensive industries such as the automotive, power generation, chemical, nuclear, and marine industries, to cite a few. In this context, briefly discuss key features of CFD modelling and simulation, focusing following aspects:

1. Numerical aspects of CD and solution of Discretized equations.
2. Numerica arid generation and convergence enhancement.
3. Turbulent flow modelling and CFD simulations in Chemical and Process
4. Engineering CD Applications in General Engineering and
5. Multiphase flow modelling.
