Non-Newtonian fluid

Objectives With the use of similar apparatus equipment through constant temperature at atmospheric pressure, the viscosity will be determined by tests in two different fluids in sets of two ball trials; along with data collected from a third set. By reducing errors and obstructions it will justify data for better discuss and calculated results, supporting the theory beyond the lab report to resonate in helping others comprehend the experiment. Procedure The experiment was…

media. The fluidized bed is when the air make the solid to behave like a fluid. For this experiment, two columns are use which one column are filled with sand and the other one filled with aluminum oxide. The bed height of aluminum oxide is 100 mm and have a particle size about 250 micron (mesh 60). The minimum fluidization velocity is used to determine the pressure drop. As mentioned above, when the solid behave like a fluid the bed is at fluidize state. So, minimum fluidization occur when the…

Computational Fluid Dynamics Computational fluid dynamics (CFD) is the simulation of fluids in engineering systems using modeling such as mathematical physical problem formulation and numerical methods like discretization methods, solver, numerical parameters and grid generation. Computational fluid dynamics is based on the concept of Reynolds averaging of the unsteady Navier-Stokes equation commonly known as (RANS) which are considered by Leishman to be the most adaptable method for…

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…

consider removing a circle of plastic from the bottom of the cup with the diameter of a regular pencil. How long will it take to drain all of the water? How much liquid is falling from the cup each second? Because of the work that has been done in fluid dynamics, we have a simple formula to help us answer these questions. Q=aC2gh In which Q represents the flow rate, a represents the cross sectional area of the hole, C is a coefficient in regards to the efficiency of liquid flow through the hole…

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…

Introduction It has been a puzzling question in fluid mechanics for quite some time as to why golf balls are designed with dimples. In the 1800’s it was discovered that a ball with scuffs in it flew through the air more consistently than a smooth golf ball.6 Manufacturers started incorporating patterns to golf balls to try and find which gave a more stable and reliable flight pattern. In the 1900’s it was determined that the strategic placement of indentations maximizes lift while minimizing…

A fluid is a substance that deforms continuously when subjected to a shear stress. A simplified definition is that it is a substance that is able to flow smoothly and changes it’s shaped when a force is acted upon it. There are different types of fluids. Ideal Fluids and Newtonian as examples. An ideal fluid is a substance that has zero viscosity and is considered to be incompressible (density is constant). [2] In reality, there is no such thing as ideal fluids as there are always viscous…
