Computational fluid dynamics

Double diffusive convection phenomenon occurs in situations where flow is driven by solutal gradients apart from thermal gradients. Present days in industrial processes like food processing, drying, chemical vapour deposition etc. the nature of fluid flow with in the process chambers largely governs the outcome. Thus research on double diffusive convection flows in relations to various applications in many mechanical and chemical engineering industries and also in fields like oceanography,…

Fluid dynamics and Bernoulli's equation Moving fluids Fluid dynamics is the study of how fluids behave when they're in motion. This can get very complicated, so we'll focus on one simple case, but we should briefly mention the different categories of fluid flow. Fluids can flow steadily, or be turbulent. In steady flow, the fluid passing a given point maintains a steady velocity. For turbulent flow, the speed and or the direction of the flow varies. In steady flow, the motion can be represented…

Friction loss is defined as the pressure loss or head loss that usually occurs in pipeline fluid flow because of the viscosity effect near the surface of the pipe. When the fluid flows along the pipeline, it produces frictional resistance thus results in loss of energy or total head loss of the fluid. Therefore, experiment was conducted to verify the Darcy Weisbach equation by determining the pressure loss along a horizontal pipe. Figure A below shows the diagram of friction loss along a…

reducing pressure or for the restricting flow. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (either liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice. But as the fluid is forced to converge to pass through the hole, the velocity increases & the fluid pressure decreases. Orifice Plate is the heart of the Orifice Meter. It restricts the flow & develops the differential pressure which is…

level a factory, or a senior research and development engineer who will use the scientific process to find cheaper, more efficient ways to produce an item, or entirely new designs and products themselves. The variety of positions available shows the dynamic nature of chemical engineering and how it can apply to many different fields. In most of these fields, there seems to be at least one thing in common, a strong ability to solve…

Abstract:The second order rotatory theory of hydrodynamic lubrication was founded on the expression obtained by retaining the terms containing first and second powers of rotation number in the extended generalized Reynolds equation. In the present paper, there are some new excellent fundamental solutions with the help of geometrical figures, expressions, calculated tables and graphs for the porous bearings in the second order rotatory theory of hydrodynamic lubrication. The analysis of equations…

Non-Newtonian fluids are plentiful in the world, both natural and man-made. Undoubtedly, they are consumed nearly every day. Foods such as cream, ketchup, honey (“Non-Newtonian Fluids”), mayonnaise, cranberry sauce, or jelly (Roth-Johnson) are non-Newtonian. For example, in order to get ketchup out of the bottle, it must be shaken. Once that has been done, it squirts out of the bottle with ease. Also, if the near-solid honey is continuously stirred, then the honey becomes more liquid than solid.…

Research This project is about what makes bouncy balls bouncy. My hypothesis is that the borax is what makes it bouncy and It will take more borax than glue to make the ball bouncier. This is important to know this because if you add too much or too less you will not have a real bouncy ball . There are three main thing we have to remember while doing this project. I will be mentioning three thing in my S.A.:Materials, Momentum, and Velocity. To make the bouncy ball bouncy it will need the…

Many of things that we interact with are solids and liquids. However, there are some things that are combination of both called a Non-Newtonian Liquid, an example of this is oobleck. This substance has the qualities of a liquid but also has the qualities of a solid when under pressure. One of its qualities as a liquid is its ability to flow, known as viscosity. In this experiment will change the oobleck’s viscosity by changing its thickness. Additionally, applying any pressure to oobleck helps…

is the resistance that a fluid has to flowing and movement. Viscosity is due to the movement of particles. The particle theory is a great tool to help us understand how viscosity works. The reason a fluid can vary in viscosity is because the greater the forces of attraction between the particles, the stronger the resistance of the particles flowing past each other will be. These terms are both related because if the fluid is very dense it will be viscous however if the fluid is thin it will be…
