The hydrodynamic parameters were determined for two different three-phase systems (fluidized-bed and trickle-bed) through the experimental evaluation of the dynamic residence time distribution in the gas or liquid phase. For different fluid phase flow rates the fluidized-bed system was operated with a tracer in the gas phase and in the trickle-bed with a tracer in the liquid phase. The analysis...

The effective heat transfer parameters in a trickle bed reactor (gas-liquid co-current downflow through packed bed reactors), ker, the effective radial thermal conductivity of the bed, and hw, the effective wall-to-bed heat transfer coefficient are estimated for air-water system over a wide range of flow rates of air (0.01-0.898 kg/ms) and water (3.16-71.05 kg/ms) covering trickle, pulse, and d...

The effects of different parameters on the hydrodynamics of trickle bed reactors were discussed for Newtonian and non-Newtonian foaming systems. The varying parameters are varying liquid velocities, gas flow velocities and surface tension. The range for gas velocity is particularly large, thanks to the use of dense gas to simulate very high pressure conditions. This data bank has been used to c...

Improvements in health result in improvements in national income, poverty could decline on account of both the standard ‘trickle-down’ effects and an increased financial capacity of nations to set up safety nets. Poverty can have an adverse impact on health because of malnutrition and also due to poor sanitation; unsafe drinking water supply etc. Odisha is an eastern state of India. Health infr...

Wall-to-bed (or wall-to-fluid) heat transfer issues in trickle bed reactors (TBR) has an important impact on operation and efficiency in this category of reactors. In this study, the hydrodynamic and thermal behavior of trickle bed reactors was simulated by means of computational fluid dynamics (CFD) technique. The multiphase behavior of trickle bed reactor was studied by the implementation of ...
