cylinderconicoil cooling

cylinderconicoil cooling

(OP)
how to calculate the natural convection of cylinderconicoil tank
1-NU no for cone part with angle =77 degree
2- relation between surfce are of half pipe coil for cooling tank and pitch

RE: cylinderconicoil cooling

Although, I don't know the internal and external fluid paths, I would explore about developing an equivalent cylindrical coil.

RE: cylinderconicoil cooling

(OP)
tank fluid is yeast
coil fluid is water
thanks

RE: cylinderconicoil cooling

"1-NU no for cone part with angle =77 degree"

This is not clear: What did you calculate for the Nussalt number for 77 degrees? Of the tank of water around the coil?
Why 77 degrees? Is the liquid in the coil 77? Or hotter?
Why are you referring to a cone?

RE: cylinderconicoil cooling

Also:

You imply the coil is inside a cooling tank, and that cooling tank apparently filled with "natural convection" water - so no pump or flow of water through the surrounding cooling water, right?
If so, what cools the water tank t? Room temperature (what temperature?) air naturally flowing around the water tanks?

Or is it the opposite: The cooling water is in the coil, and the tank is getting cooled by the water flowing in the coils, but the tank has no pump or stirring paddle? If so, what temperature water is flowing in and out, at what flow rate?

RE: cylinderconicoil cooling

(OP)
i want to cool cylindroconical tank with water in outside half pipe jacket
flow in jacket is water inlet temperature 27c and outlet 33c
q= 120 kw generated and transpeted
q=u*A*delt T log
so, what is surface area of half pipe jacket

thanks
