The aim of this study was to investigate the effect inserting a new internal tube packing (TP) on thermal performance thermosyphon heat pipe (THP). THP made from copper with an inner diameter 17.4 mm and length 600 mm. had central disc two tubes soldered onto both sides transport vapor condensate. upper or riser 8.3 300 long; it connected hole in side steam condenser section. lower downcomer 5 ...

The objective of this study was to investigate the hydrodynamics and gas-liquid mass transfer coefficient an external-loop airlift reactor (ELAR). ELAR operated in three cases: different inlet velocities fluids, alcohols solutions (water, 0.5% methanol, ethanol, propanol butanol) concentration methanol (0%, 0.5%, 1%, 2% 5%). influence superficial gas velocity various diluted alcohol on studied....

The kaolin suspension calcination technology is currently gaining attention as a new process of calcining kaolin. In this paper, the cooling system designed by CBMI Construction Co., Ltd. simulated using ANSYS Fluent software to analyze velocity field and temperature gas–solid two-phase flow Eulerian model. A compiled UDF (User-Defined Function) used simulate transfer mass heat from downcomer t...

Turbulent mixing in buoyant flows is an essential mechanism involved many scenarios related to nuclear safety power plants. Comprehensive understanding and accurate predictions of turbulent the reactor are crucial importance, due function mitigating potential detrimental consequences during postulated accidents. The present study uses URANS methodology investigate buoyancy-influenced pressure v...

Spirals as internals are utilized to reduce the axial mixing of solids in fluidized beds, by routing the solids flow in a predetermined route or by localizing the solids mixing. The drying kinetics of continuous fluidized bed with and without internals has been compared and modeled using batch drying kinetics and residence time distribution analysis. The batch drying experiments were conducted ...
