I need an Ansys expert who can simulate the flow through a Venturi scrubber. The project is based on the removal of air pollutants present in a stream of air using household water as the scrubbing liquid. The water is to enter through the throat of the venturi scrubber and the dust laden gas will enter through the converging section of the scrubber.
The aim of the simulation is to study the hydrodynamics especially at the throat section when the air and water interact at the throat and hence develop the pressure drop profiles.

Help me design and calculate a refrigeration system to cool down a hydroponic liquid in a cooler box. The design would be like in the sketch of the attached files. The inner diameter of the cooler box is 38(L) x 23(W) x 22(H)cm and the outer diameter is  L46 cm x W32 cm x H27 cm.
Can you:
- find the cooling load needed to cool down a 16 litre of water at a constant flow rate of 1 litre/minute so that the temperature could maintain 12°C  when it flows out of the outlet plug drain below the cooler box. 
- Determine the suitable size and height for 4 plug drain to be position at each side of the cooler box, so that the flow rate could achieve 0.25 litre/minute for each of the plug drain. (Flow rate: 0.25litre/minute X 4 = 1 litre/minute)
- determine the right length, the number of coils, and pressure of the copper coil (as an evaporator to be submerged in the 16-litre water) so that it could achieve the cooling load needed to cool down the water to 12°C.

(Guide: Set evaporator pressure such that the saturated temperature of the refrigerant is 15°C below inlet temperature of water [Find inlet water temperature = heat from the atmosphere (30°C) + heat gain during the pump delivery]
- conduct fluid dynamic analysis on the connecting pipe to determine the pump power and the diameter of the delivering pipe.
- Set pressure of condenser of refrigeration plant such that the saturated refrigerant temperature is about 12 degrees C above atmospheric temperature.
-Conduct heat transfer analysis at Hydroponic Liquid and the Refrigerant in the evaporator to determine the flow rate of refrigerant.
-Calculate the power of compressor that operates between condenser and evaporator pressures.
-Determine the size of air-cooled condenser.
-Determine the size of the expansion valve.
