hello i want to model and analyze a 2d river which passes a step, in fluent and gambit, but i don't have any idea how should i define free surface between water and air, here is my geometry: i really appreciate if anybody can help me.

my background in math and physics are lessons i have passed in my bsc: general math 1 general math 2 differential equations engineering mathematics general physics 1 general physics 2 some other lessons i have passed in Naval architecture: fluid mechanics 1 & 2 heat transformation 1 what was...

Hello I have bachelor of science in Naval Architecture and i want to study mechanical engineering "Thermo fluids" for Msc,my question is: because i have bachelor of Naval Architecture,i have not passed about half of lessons mechanical engineers pass during their study.so i think i need to read...

i can confirm that your answers were right,but i think there is an exception,if you cut the piece in this way: -EF and HG can have any length -Eh and FG are cut so that their length is equal to AC or BD,i mean if AC and BD are for example 1 [m],EH and FG are cut so that their length is 0.99999...

you were near the right answer but i have another opinion, i will give it away tonight.

hello fluid knowers! here is a question i have asked from several students every time a different answer was given to me. now let's see what is your answer mechanicals! question: we have a steel block floating in mercury as shown below...

thank you so much Q_Goest and FredGarvin,i think i have my answer now.

here is the link: http://www.jeffree.co.uk/pages/taigcncpt1.htm you said "there are better(efficient as well as cheap) options." do you know some of them?

thanks for answer.i know "Its a coupling for parallel shafts at some radial distance",i want to know name of some machines that use it,searching in google i found that it is used in cnc machines,is there any specific other machines that use this couplig? you said it works in labs now,you mean...

hello our prof talked about oldham coupler and showed us some animations of how it works, but didn't mention about where and in which machines it is is used, anybody knows some practical uses of oldham coupler and some examples of machines this coupler is used in? thanks
