I want to find some force data for fluid stirring. originally I intended to record the data using my force sensor, but it doesn't have the resolution to read stirring force for Newtonian fluid.
unless there's a Newtonian fluid with high enough viscosity to produce a reaction force greater...
just wondering, is there any place where I can find existing force data on fluid stirring? I have a force sensor but it won't register anything under a Newton. stirring water won't even beat the noise values, so I am hoping there are existing data I can use as reference
thing is, I already have SPH program, is there no reasonable way to add the effects of the stirring force into my numerical solution?
my lagrangian navier stokes equation is already much simplified. the momentum equation has 3 terms, pressure, viscosity, and external force.
surely there...
can you link me to the procedure to approach this problem? I realized too that this must be solved in the Navier Stokes equation, not just simple collision detection like walls and stuff, but I don't know how the forces work in that perspective since I am pretty new to fluid mechanics myself. thx
when you stir fluid in a beaker of fluid, how is the motion on the fluid by the stirring rod calculated?
the fluid is represented using smoothed particle hydrodynamics lagrangian method so that I can look at fluid as a bunch of spheres interacting with each other through a sort of force...
Homework Statement
assuming the path of the ball is linear, if the ball collides with the cube, I want to find which side the cube the ball collided with. this is a discreet problem, the ball's position and velocity are always known. the cube's size is bigger than the ball's size in the way...
I am having some confusion in computation fluid dynamics. navier-stokes equation is the differential equation for fluid motion, but does this equation apply to gas as well? to my understanding gas qualifies as a fluid but I am having trouble seeing how the same equation applies to both liquid...
what kind of math language is this?
$I\subset \reals$
$$\gamma_i:I_i\rightarrow M,\quad I_i\subset\reals,\quad i=1,2$$
$\sigma_{\alpha\beta}$ , let $$\rJ\sigma_{\alpha\beta}:V_{\alpha\beta}\rightarrow \Mat_{n,n}(\reals)$$
I have seen this notation thrown around in this forum, but I never...

The Attempt at a Solution
I already know the solution but I don't understand what it means
the process is simply fixed(c,b,a) to euler(a,b,c)
Rz(a)=Rz(a)
Ry(b)=Rz(a)Ry(b)Rz'(a)
Rz(c)=Rz(a)Ry(b)Rz(c)Ry'(b)Rz'(a)
write it in fixed...
need a list of books for general reference for the future. currently a master level engineering student, I went through undergrad with some confusing books and I want to acquire some modern books on individual topics that are well received.
for specialized topics, I am in need of introductory...
is damping usually introduced in velocity or displacement?
if displacement reaches stable condition first, wouldn't velocity still be fluctuating because velocity calculation does not involve displacement at all?
or should the damping go into the force calculations in SPH?
can you simply extract the elasticity from ultrasound medical images? I don't know ultrasound very much but I just found out it can measure elasticity.
under what condition can ultrasound be used to measure elasticity of some deformable object and do ultrasound medical images qualified for...
