I am designing a machine which part of it is make of a reciprocating pump as the attachment.
So I am wondering if solidworks can help me to simulation the motion + flow inside the reciprocating pump??
Welcome to SW forums Kevin.
I believe you can use combination of SW Motion and Flow analysis to accomplish this.
is that mean I first do the motion part??
and use the result to do the flow simulation??
Yes use motion analysis first and then import the results into flow simulation. Though I'm not a FEA person but believe this is a way to do it.
to do this with high fidelity you would ideally need a moving mesh capability in Flow sim which it does not have. You could simulate the motion with motion and you could come up with some approximation of the flow at some instant in time. The BC's would be a bit tricky. That is about all you could hope for in my humble opinion but others may have thought about it more to give more concrete techniques on what you might be ale to pull off. Pretty dicey at best.
We Can't do dynamic flow simulation in the solidworks flow simulation.
Solidworks motion supports only kinematic or dynamic mechanism only, in this we are not going to define any fluid etc.
My openion if you looking the final results means, take the wrost condition i.e. position of the piston rod, then apply the suction pressure and outlet condition which is you know. then see the flow, pressure action on inside the parts.
second option is use parametric study in Flow simulation, there we change change the position of the piston, But it will create the configurtion with different positions, then you can able to find the flow parameters .
Thanks & regards,
oh, then what is the use of moving wall in BC??
btw, should i use fluent or CFX to do this task instead of sw??
moving walls are for friction effects on the fluid - i.e. if you want to simulate a car on a road
if you have the car and road and apply air currents to simulate the car moving it is simply wind blowing against a stationary car. Moving walls let you say that the road is moving the same speed as the air (so there is no relative motion between air and ground which makes it appear the car is moving).
You can define a moving wall as a non-zero velocity wall. It can be done as long as the mesh does not have to change to describe it. Piston in a cylinder or a moving tweeter of a speaker cannot be modeled because they would require a moving mesh.
Some pertinent uses have been given, such as: a moving road, or a driven cavity (like in one of the validation examples), and I have also used it to simulate a tire's rotation because it can also be an angular velocity (be careful here that the geometry has to be a revolve, so no treads or fancy rims for example).
Check out CD-adapco and Cradle-CFD offerings too.
If there are no chemical reactions, this can be a typical FSI problem. Either you can use dynamic mesh in FLUENT. Or use new FSI co-simulation feature in Abaqus (if flow is incompresible).
