This paper presents a validation study of a multi-physics coupling code for solid fuel pyrolysis in solid-fuel ramjet engine (SFRJ). An in-house code has been developed to model flow, turbulence, heat transfer, solid pyrolysis, and chemical reactions. Unsteady reacting simulations are performed for swirling and non-swirling flows in SFRJ with high-density polyethylene solid fuel cylindrical grain...
Due to the widespread use of incineration as a method of waste disposal for solid waste, it is important to have a detailed mathematical modelling and understanding of the incineration process. In this paper the governing equations for mass, momentum and heat transfer for the gaseous phases of the incinerator furnace are described and relevant sub-models are presented. The solid waste bed is assumed...
CFD(Computational Fluid Dynamics) numerical simulation method was adopted to study on the solid expansion character in flow process of two phases fluidized bed including liquid and solid phases and testify the reliability. Commercial CFD software-Fluent was used in the study under some proper boundary conditions, such as velocity inlet, pressure outlet, symmetry condition for free liquid surface,...
A novel annular spouted bed with multiple gas nozzles, has been proposed for dryness, pyrolysis, and gasification of coal particulates. It consists of two homocentric upright cylinders with some annularly located spouting gas nozzles between inner and outer cylinders. A three-dimensional Eulerian multiphase model, with closure law according to the kinetic theory of granular flow, was used to simulate...
