Experimental and analytical techniques have limitations in fluid mechanics applications. Computational fluid dynamics (CFD) uses numerical methods like finite difference, finite element, and boundary element to solve the governing equations at discrete points within a domain. It allows for complex simulations that would be difficult or expensive with physical experiments. CFD involves discretizing the domain with grids, solving the equations numerically, and analyzing the results to obtain approximate solutions for fluid flow problems.

The document discusses different types of welding processes including thermite welding, electron beam welding, solid state welding, cold welding, and ultrasonic welding. Thermite welding uses an exothermic reaction between aluminum and iron oxide to reach temperatures over 3000°C to melt and join metal parts. Electron beam welding uses a high-energy electron beam in a vacuum to melt and fuse materials. Solid state welding joins materials without melting them through processes like cold welding and ultrasonic welding.

Thermoforming is a process where a heated plastic sheet is formed into a desired shape using pressure, vacuum, or mechanical methods. The key steps are heating the sheet, clamping it, and forming it using pressure or vacuum against a mold. Common applications include packaging, bathtubs, and large parts. Mass production uses thermoforming for thin packaging like blister packs while thicker sheets make larger parts like machine covers or boat hulls.
Extrusion is a process where a billet is forced to flow through a die opening under high pressure to produce a part with a constant cross-section. Common materials extruded include metals like aluminum, copper, steel, and plastics. The extrusion process begins by heating the billet and placing it into an extrusion press where a ram pushes it through a die. Direct extrusion uses a stationary die and moving ram, while indirect extrusion has a movable die within a hollow ram. Extrusion can produce complex shapes and is used to manufacture parts like tubing, profiles, and frames.

The document discusses heat treatment processes for engineering materials. It describes how heating and cooling can be used to alter the structure and properties of materials, primarily metals. Key points include:
1) Heat treatment involves controlled heating and cooling to change a material's microstructure and properties in a way that does not alter its overall shape.
2) Common heat treatments include hardening, annealing, normalizing and tempering. All involve heating, holding, and cooling, which can result in phase transformations.
3) Phase transformations in steel depend on the alloy's carbon content and the heating/cooling rates. Rapid cooling can form martensite to increase hardness, while slower cooling forms pearlite or ferrite/
