knowledge of fluid flow can play a basic role in optimizing mixing processes. in preparation of sodium perborate, sodium metaborate and hydrogen peroxide, as raw materials, mix and react in the presence of a turbine mixer. in this investigation, the effect of the presence of baffle in a mixing tank equipped with a two-impeller turbine agitator was studied. at first, steady state flow in the tan...

A model scald tank was constructed to study the mixing pattern of water in a poultry scalding system. Tank dimensions were approximately 6 m long by 10.5 cm wide with a water depth of 18 cm. Water was vigorously agitated with compressed air delivered through a 1.9-cm polyvinyl chloride pipe on the bottom of the tank. Food coloring was added to the tank at a single point, and water samples were ...

The paper focuses on the data collected from the mixing of shear thinning non-Newtonian fluids in a cylindrical tank by a Rushton turbine. The data presented are obtained by using Computational Fluid Dynamics (CFD) simulation of fluid flow field in the entire tank volume. The CFD validation data for this study is reported in the research article 'Numerical investigation of hydrodynamic behavior...

This study investigated the main factors influencing digester temperature and methods to reduce heat losses during the cold season in the subtropics. Four composite digesters (two insulated and two uninsulated) were buried underground to measure their internal temperature (°C) at a depth of 140 cm and 180 cm, biogas production and methane (CH4) concentration in biogas from August to February. I...

Mixing tanks equipped with mechanical stirrer are broadly applied in chemical and petrochemical industries, due to their variety of industrial process requirements. In this study, helical single blade mixer was designed applying CATIA and then mixing of fluid and solid particles, in a tank with this agitator was examined by OpenFOAM. For velocity distribution in the mixing tank, continuity, mom...

In this color mixing machine we use three tanks which are of Red, Blue and Yellow. The three tanks consist of level sensor and fitted with hydraulic line. The hydraulic line consist of solenoid valve.The tank consists of color Steiner of Red, Blue and Yellow. The Steiner flows from hydraulic line into the mixing tank through solenoid valve. The solenoid valve is a digital output device that is ...

Thermal energy storage is an essential component of solar heating systems. A numerical analysis of thermal stratification in hot water storage tanks suitable for solar water heating applications is presented in this paper. Transient, axi-symmetric, turbulent natural convection in fully and partially charged storage tanks for varying Rayleigh Number in the range of 10 to 10 is studied. Mix Numbe...

In this work, the results of mixing study by a jet mixer in a tank have been investigated in the laboratory scale. The tank dimensions are and the jet entrance have been considered in the center of upper surface of tank. RNG-k-ε model is used as the turbulent model for the prediction of the pattern of turbulent flow inside the tank. For this purpose, a tank with volume of 110 liter is simulated...
