What is Fluid flow: Definition and 213 Discussions
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation.
Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.
Before the twentieth century, hydrodynamics was synonymous with fluid dynamics. This is still reflected in names of some fluid dynamics topics, like magnetohydrodynamics and hydrodynamic stability, both of which can also be applied to gases.
Hi all,
I've been stumped on this problem for over a month. Any guidance would alleviate my overwhelming frustration. Here is the original problem statement:
Find the principal rates of deformation and principal axes for the flow given by: u = (x,y) and v = 0, satisfying the...
:zzz: hello
NEED COMPLETED INFORMATIONS ON NOZZLES(FROM FLUID MECHANICS POINT OF VIEW)PLEASE GIVE ME NAMES OF SOME WEBSITES WITH MATERIAL ON NOZZLES IN PDF,OR POWER POINT SLIDES OR ANY OTHER WITH EFFICIENCY INCREASE CALCULATIONS
WAITING FOR PROMPT ACTION
THANKS
Hello,
I cannot figure out which pump or size of pump would fit the need I have. Can you please review the need and recommend a type and pump model/specification that you think would work for this application?
I need to have a fluid flow of these specs, I don't have any constraints or...
This came up in the homework help section, and has me scratching my head.
Consider a vertical pipe open to atm at one end under steady flow.
The velocity in has to be equal to the velocity out because of the cont. equation.
The pressure at the bottom is zero, (atm), and the datum is at...
I'm struggling with this question right now:
Let the complex velocity potential \Omega(z) be defined implicitly by
z = \Omega + e^{\Omega}
Show that this map corresponds to (some kind of fluid flow, shown in a diagram, not important).
For background,
\Omega = \Phi + i\Psi...
I'm trying to create a model of the procedure of having a bone marrow biopsy done in order to seek ways of eliminating the pain which one has to endure during this process. I'll need to start with modeling fluid flow in a porous medium but this is something I've never done before and have never...
Ive been thinking a lot and come nowhere, is it possible to create a program with a 2D envirment where the temperature change from place to place and make the computer calculate a current in the fluid? if so how would the mathematic look like then?
hi guys
if you have an aluminium sphere of volume 0.006 metres cubed, how do you find the gravitational force acting on the sphere, as well as its acceleration (ignoring water resistance)
Also, if your given the area and velocity of a fluid at two points of hose, how can you find the...
I need to do some fluid flow calculations at low Reynold numbers. My current PIII won't suffice. Which processor should I go in for?
I was looking towards the likes for P4 3GHz with HT. I know with this speed, the calculations will take hours but I am willing to tolerate that. Will a 3.2 GHz...
I need badly some materials or instructions on how to simulate fluid flow or similar/related things to finish my research in the next 3 months...Do you know where I can find some to read, or places where I can download source code ?? Anything about it is really fine, how to simulate is also...
I have a sylindrically shaped canister (open from the top) with a height of 25.0cm and a radius of 5.00cm. At the bottom there is a hole with an area of 1.50cm^2 spraying out water. How long does it take to empty the canister?
Subscripts t and b stand for top and bottom and h is the height...
I need help. My associate called from the job site and said,
"This building we're inspecting in Alaska had a 1/2" pipe freeze and then completely broke open at the compression ring. Water was freely running over the weekend. How many gallons per minute do you think was being dumped?"...
I'm in the process of designing a scoop used for automotive purposes. Anybody know some formulas pertaining to pressure, velocity and area dealing with scoops (Funnels, cones, etc)? Thanks for the help! Joe
