A zonal model for radiation heat transfer in coal-fired boiler furnaces
… a radiation heat transfer network solution methodology based on the zonal method that may be applied to boiler furnace modelling. The zonal method allows for the prediction of heat flux and temperature distributions on the walls, inside, and at the exit of the furnace. Direct exchange areas …

Development of methods to predict the discharge capacity in model and prototype meandering compound channels
The author developed two methods for predicting the discharge capacity of uniform meandering compound channels. The first method utilised an Artificial Neural Network (ANN) functional approximator which was taught to replicate the relationship between 9 of the key parameters and the magnitude of F* …

Unstructured finite volume algorithms for compressible multiphase flow
… successfully run with the diffusion correction methods, variable bounding and proper under-relaxation practices. The applicability of a pressure interpolation method has also been tested with these cases. A procedure for solving compressible flow within a finite volume, pressure correction type …

A thermofluid network-based methodology for integrated simulation of heat transfer and combustion in a pulverized coal-fired furnace
… dynamic simulations. A thermofluid network-based methodology is proposed that combines the zonal method to model the radiation heat transfer in three dimensions with a one-dimensional burnout model for the heat generation, together with characteristic flow maps for the mass transfer. Direct …

Image based analysis of visibility in smoke laden environments
… without the high cost typically related to zonal method and the limitations in discrete ordinate method. The algorithm has been combined with a two pass solution method to produce high resolution images without introducing excessive number of rays from the light source. The convergence of …
