Integration of a Population Balance Model into Bubble Column: CFD Approach
Abstract: A computational fluid dynamics (CFD)-code ANSYS FLUENT 15.0 has been implemented using finite volume method in eulerian framework for the simulation of axisymmetric transient flow in bubble column. The population balance has been included to solve for the bubble flow and size distribution for the population of six different bubble sizes in the CFD code. A fixed pivot method of Ramakrishna [ANSYS FLUENT 15.0] has been used to discretize the …

Study of Energy Conversion System Using a Magnetic Fluid: An Overview
Abstract: Magnetic fluids have promising potential for direct energy conversion system. Magnetic fluids are stable suspension of nano-sized ferromagnetic particles in suitable non-magnetic carriers like kerosene, organic liquids, water etc. The typical curie temperature of magnetic particles is controlled by selecting constituents of the ferromagnetic material. There are large numbers of practical applications of magnetic fluids in various fields ranging from engineering to medicine. A thermomagnetic device gives an idea of …

Numerical Investigations of Fluid Flow and Heat Transfer in a Ribbed Heated Duct with Variable Aspect Ratios
Abstract: The present investigation has been carried out to investigate the steady-state forced convection heat transfer and pressure drop characteristics of turbulent flow in an air cooled horizontal duct. The aspect ratio (W/H, where W is width and H is the height of the duct) is varied in the range of 1 to 4. Square ribs are fixed on the inner side of the bottom wall which is heated with constant …

Mould Cavity Thickness Effect on Aluminium Solidification for Temperature Dependent Properties
Abstract: Effects of the mould wall thickness on the solidification and heat transfer have been studied in the present paper. Aluminium in pure form and green sand has been adopted as a molten and mould cavity material respectively. Aluminium thermal properties are considered to be temperature dependent. Casting products have been used in many industries and household applications. Solidification and heat transfer during casting are crucial events which have been focused …
