Hello

 

i want to develop blending tank for thinner mixing with multiple impeller. i already study the literature and design the mixing tank. but i dont know how to validate my design. i afraid it is different from the reality.

is that any suggestion or way to validate my design?

 

Thank you

 

Regards,

Andrew

Computational fluid dynamics can be a better validation than prototyping. I am wary of scale models for mixing, but they are better than nothing.

Andrewnomix,

Excuse me, can you give more information about your design?, for example volume to mixing, and other considerations (only an exercise). Normally thinner has a low viscosity...maybe you don't need a multiple impeller.

Hi andrewnomix,

why don't you call vendors ( big names) to design an agitator for your application , submitting to them the necessary information about your product, the time required, etc....?

Take a look at the link attached ,

An example of big names : Lightnin or Leva (chemineer)

Hello Napo

 

the tank diameter is 2.2 meter

volume is 15 kilo liter

and the tank height is 4.2 meter

 

my impeller diameter is 0.74 meter

 

what kind of impeller i have to use? i want to avoid electrostatic. 

 

Thank you

Thank you, but it's hard to find any vendor on my place that i live.

Hi ,

To support your work a few documents .

 

To minimize the fire hazard you need to consider Inerting and earthing , plus the right classification of motor for flammable material .

 

Good luck,

Andrewnomix,

 

Breizh´s information it´s excellent!!

 

A reference for select the impeller type is: "Select the Right Impeller" by J. Fasano, from Chemical Engineering Progress (June, 2015), p-. 30-36. I attached the Table 1 from this article.
