Supercritical flow

toward more supercritical flow, the ratio of the D2/D1 i.e. ratio of the downstream depth to the upstream depth also increases. It is also evident from the graphs that approximately 97% to 100% of the calculated results all lie within the ± 10% of line of best fit for each curve. As well, each of the graphs verifies a strong positive linear relationship between the dimensionless jump height and the upstream Froude Number. These results imply that a more supercritical upstream flow in D1, will

Hydraulics of Submerged Radial Gates with a Sill Abstract In this paper the submerged flow through radial gates with and without a gate sill was experimentally investigated. The effect of different gate sill heights on contraction coefficient, discharge coefficient, submerged jump length, backup water depth, flow energy dissipation, and velocity distribution with different hydraulic parameters were analyzed and graphically presented. A combination of dimensional and regression analysis tools was

Hydraulic Jump Experiment SUMMARY The Objective of this experiment is to observe the flow patterns and behaviour of the water before after the jump Also to quantify the energy lost due to a hydraulic jump. The observed and theoretical ratios of upstream and downstream depths will be compared, this will show the limitations to purely theoretical analysis. The experiment showed that a hydraulic jump occurs when when liquid at high velocity discharges into a zone of lower velocity

Pressure Management on a supercritical aerofoil in transonic flow Abstract-At transonic speeds an aerofoil will have flow accelerate onwards from the leading edge to sonic speeds and produce a shockwave over the surface of its body. One factor that determines the shockwave location is the flow speed. However, the shape of an aerofoil also has an influence. The experiment conducted compared Mach flow over a supercritical aerofoil (flattened upper surface) and a naca0012 aerofoil (symmetrical).

INNOVATION OF HYDROTHERMAL SYNTHESIS FRON THE PAST & PRESENT Traditional Hydrothermal Synthesis since the end of the 19th century, hydrothermal synthesis of inorganic materials has been carried out. It is defined as the precipitation of these materials from aqueous solutions at temperatures above the boiling point and at pressures greater than ambient pressure. This method is actually environmentally because it does not require any organics or additional processing such as calcinations. That is

Essential oils are natural products formed in aromatic plants which are characterized by unique features of odor and flavor for their own benefits such as protection or attraction (7). The oils are accumulated in cells, located in tiny secretory structures or in glandular hairs of the plant. The interior of the stomatal cells is typically the location of where the essential oils are found. While they are located within the plant, essential oils are continuously altering their chemical composition

Extraction, as the term is utilized pharmaceutically, includes the partition of restoratively dynamic segments of plant or creature tissues from the idle or latent parts by utilizing particular solvents as a part of standard extraction strategies. The items so acquired from plants are generally polluted fluids, semisolids or powders expected just for oral or outside use. These incorporate classes of arrangements known as decoctions, implantations, liquid removes, tinctures, pilular (semisolid) separates

Jiaxin Cheng LSU ID: 893952268 ENGL 1001 21/09/2016 Dear Professor Csikszentmihalyi, This letter is talking about what I learned from your book, my flow experiences and what are elements of flow in my opinion. But before that I would like to share a old Chinese fairy tale with you. 1800 years ago in Jin dynasty of China, there was a farmer who’s name is Wangzhi. One day he went out to cut firewood in hills, he saw there are an old man and a child playing the GO (a Chinese game) in pavilion

"The opposite of love is not hate, it's indifference. The opposite of faith is not heresy, it's indifference. And the opposite of life is not death, but indifference between life and death." - Wiesel

Apathy Indifferent. Detached. Desolate from any kind of emotion. This is how one “feels” when apathy sneaks its way into their brain. Everything they have ever felt becomes a vague and distant memory, a vast void. There is nothing that can be done, so it seems to the individual. This leaves him/her quite helpless. And more often than not, the phrases “I don’t care!”, “Why does it even matter?”, and “It isn’t important” are overlooked and are labeled rebellious. But should those phrases not spark
