In this study, a coil heat exchanger with an ice storage system is analyzed by theoretical analysis, numerical analysis, and experimental analysis. The dynamic characteristics of ice thickness variation is studied by means of unstable heat conduction theory in cylindrical coordinates, and the change rule of the ice layer thickness is obtained. The computational fluid dynamics method is employed...

The work on the quality improvement of fuel oil using acid treatment was carried out. The improvement of the fuel oil was done using sulphuric acid to remove contaminants. Sulphuric acid at different concentrations were mixed with the oil and kept at 45°C for four hours in the agitator vessel to allow reaction to take place. Acidic sludge was then drained off from the agitator and the oil was n...

• Dynamics of driven ATR characterised experimentally and numerically. Optical acoustic methods agree well with LBM numerical model. Mixing regime depends strongly on applied amplitude, a , agitation frequency, f . power number increases re as 2 3 above critical value. Agitator tube induces fluid wakes, motion closely coupled to velocity field. This study investigates the dynamics novel, oscill...

Abstract Aristek Highpolymer is a company that produces emulsion polymers and synthetic resins. In the production process, R301 agitator has often experienced overheating, which disrupted process caused damage to mixer engine motor. Currently, checking temperature on Agitator been done manually using thermo-gun information be hampered several times stirrer motor go off. For this reason, study d...
