Co-combustion of biomass or waste together with a base fuel in a boiler is a simple and economically suitable way to replace fossil fuels by biomass and to utilise waste. Co-combustion in a high-effic...
Analysis of Heat Transfer for Laminar Flow in Concentric Pipes
Concentric pipe heat transfer enhancement non-staggered grid finite volume
2009/10/14
In this study, laminar flow and heat transfer in a circular pipe with an inner tube inserted was investigated numerically. For this reason, two-dimensional Navier-Stokes, continuity and energy equatio...
TEST OF TOTAL HEAT FLUX FROM WOOD CRIB FIRE IN AND OUTSIDE COMPARTMENT
wood crib total heat flux ISO 9705 Room
2009/10/14
Performance-based design for passive building fire safety provisions is accepted by the authority in Hong Kong since 1998. This is also known as the "fire engineering approach", though the performance...
COMPARISON OF CALCULATION METHODS FOR SMOKE AND HEAT EVACUATION FOR ENCLOSURE FIRES IN LARGE COMPARTMENTS
enclosure fires smoke and heat evacuation calculation methods
2009/10/14
A comparative study is presented of different calculation methods with respect to the evacuation of smoke and heat in the case of enclosure fires in large compartments. These methods range from manual...
The paper presents overview of the current state of fire suppression studies. Focus is made on water-based fire protection technology, such as sprinklers and mist systems. Mechanisms of suppression an...
AN INVERSE STEFAN PROBLEM RELEVANT TO BOILOVER: HEAT BALANCE INTEGRAL SOLUTIONS AND ANALYSIS
fire boilover Stefan problems
2009/10/14
Stefan problems relevant to burning oil-water systems are formulated. Two moving boundary sub-problems are defined: burning liquid surface and formation of a distillation ("hot zone") layer beneath it...
The research presented consists of a study of the burning characteristics of a liquid fuel floating on water with emphasis in the phenomena known as boilover. The problem is of technical interest in t...
LARGE-SCALE POOL FIRES
pool fire spill fire radiation
2009/10/14
A review of research into the burning behaviour of large pool fires and fuel spill fires is presented. The features which distinguish such fires from smaller pool fires are mainly associated with the ...
THE EFFECT OF SURFACE REGRESSION ON THE DOWNWARD FLAME SPREAD OVER A SOLID FUEL IN A QUIESCENT AMBIENT
flame spread polymethyl methacrylate surface regression
2009/10/14
The present work is addressed to the numerical study of the transient laminar opposed-flow flame spread over a solid fuel in a quiescent ambient. The transient governing equations - full Navier-Stokes...
