Fluid means study of a substance that continually deforms (flows) when shear stress is applied. Fluids includes liquids, gas and plasma. In fluid mechanics the study of fluids and forces on them. Fluids mechanics has three main fields they are namely fluid static the studies the fluids are at rest, describe the fluid motion and its consequences without considering forces causing the motion. Fluids kinematics that studies the effect of forces on fluids motion. These fields are very important when it comes to subject like aeronautical engg. civil engg. etc. These are three approaches to fluids mechanics-experimental, theoretical and computational approach. Experimental approach is the oldest approach where you will make measurements using equipment’s but this is costly. Then we have theoretical approachwhere we apply the mathematical equations. Mathematical equations that goes on the flow and try to capture the fluidic behavior with within a closed form solution i.e. Formulas that can be readily used. Limitation come when the result equations may be too complicated to solve easily. Then comes computational approach. Here we try to solve complicated governing equations by computing them using a computer. In the recent year computational fluid dynamics(CFD) has become a very powerful approach in industry and research. It is the branch of fluid mechanics that uses numerical method and algorithm to solve and analysis the problem involved in the fluid flow. Computers are mainly used to simulate interaction of fluids with surfaces defined by boundary conditions.
