Sorry, i meant that would the reduction of the height of the inner tank (Z2), thus creating a head difference between the inner and outer tanks, be proportional to reducing the height of the transfer pipe (Z3) to a level that was equal to or less than the height of the sand (Z5). i'm finding it...

i'm not sure i understand?

Sorry i had forgot about this problem, take a look at the crude excel drawing which shows the tank setup, with an updated description. Z1 being the outer tank height half filled with liquidized sand on the bottom and water on the top, Z2 being the inner tank which the material will transfer to...

Hi guys, got a little problem I'm currently working on and looking for some input/sanity check. Firstly i have a round tank within a round tank both with open tops, the inner tank is suspended within the outer tank such that there is a gap between both tanks bottoms faces, the inner tank open...

The formulas for the X and Y co-ord in my model were taken from the Yamamoto book. Yamamoto, K 1971. Rotary Engine, Toyo Kogyo Co ltd, Tokyo. X = e.Cos(3(O))+RCos(O) Y = e.Sin(3(O))+RCos(O) where e = eccentricity R = Rotor radius O = Angle in radians the angle is progressed from 0-360 at...

yes sorry, i misread the original post. perhaps a centrifugal turbine much like that used in a turbocharger would be a good option.

have you looked into swash plate pumps?

here is a quick video of my model in action

your in luck, i built a model rotary engine as part of my second year project in my Mechanical Eng degree. it is a difficult shape to machine but i have the two driving formulas which locate the tip of the rotor at any point in the cycle. here is my solidworks model i drew my rotor pocket...

thanks for the reply, from your username i assume that you like the odd wankel every now and again. As my second year project i designed, machined and assembled a model rotary engine for demonstrating transformation of motion, check out LYIT Wankel engine on youtube, i have a project report...

Hey guys, long time reader first time poster. I'm undertaking a project in partial fulfillment of my Mechanical Engineering degree with regards to the cooling of an intercooler heat exchanger with an exterior water spray. basically i have an intercooler and i am using a hair dryer to supply a...
