Reciprocating Compressors

Image
Introduction   Compressors are mechanical devices that are used to increase the pressure of a gas or air by reducing its volume. They work by drawing in low-pressure gas or air and then compressing it into a smaller volume, which increases the pressure of the gas or air. Compressors play a vital role in many industrial and commercial applications, and they are designed to operate efficiently and reliably under a range of operating conditions.   Positive displacement compressors and dynamic compressors are the two main categories of compressors. Positive displacement compressors work by trapping air or gas in a chamber and then reducing the volume of the chamber, which increases the pressure. Reciprocating compressors use a piston and cylinder, while rotary compressors use gears or lobes to compress the gas. Dynamic compressors, on the other hand, use high-speed rotating impellers or blades to accelerate air or gas and convert the kinetic energy into pressure energy. Cent...

Green Hydrogen

Image
    Green Hydrogen Introduction to Hydrogen We know that Hydrogen is a colourless and odourless gas.   Now a days, this gas is becoming popular as clean and convenient burning fuel. This colourless and odourless gas can be stored as liquid or a compressed gas. It is very versatile in nature. Because of which it can be used for everything, from the production of plastics and fertilizers to powering cars’ internal combustion engines. Hydrogen has to be extracted by a chemical process from its other compounds as there are no deposits of natural hydrogen on earth. The vast majority (around 95% of the word’s hydrogen) is produced using fossil fuels, either by using natural gas (through a process known as SMR i.e., steam methane reforming) or using a coal gasification process. But these methods are not the clean ways to produce hydrogen . The clean way to produce hydrogen is through a process called electrolysis. We know that water is made up of hydrogen and oxygen atom.

CFD and its Use in Hydraulic Machines

Image
CFD and its Use in Hydraulic Machines What is CFD?       CFD stands for Computational Fluid Dynamics. It is a branch of CAE which stands for computer-aided engineering. It is based on the Navier-Stokes equations and its basic principles. It gives numerical approximation to the equation that governs fluid motion. It deals with heat transfer problems and fluid flow problems. CFD analysis allows engineers to visualize, test and analyze their product designs for problems related to fluid flow, heat transfer, turbulence, non-Newtonian materials, etc. by simulating exact working conditions. A CFD model gives you a good idea of ​​how the system will act at the design stage. It shows what will work and what won't, and allows you to intervene early before anything has been constructed. Fig 1. CFD      CFD technology is an advanced virtual design method, which simulates the influence of the structure on its pe...
