Australia has experienced a sudden and unexpected resurgence in bed bug infestations from both Cimex lectularius L. and Cimex hemipterus F. A survey in 2006 revealed that infestations had increased across the nation by an average of 4,500% since the start of the decade. In response, a multi-disciplinary approach to combat the rise of this public health pest was implemented and involved the coor...

In this study, a 2D model for a CFB biomass combustor has been developed which integrates and simultaneously predicts the hydrodynamics, heat transfer and combustion aspects. Combustor hydrodynamic is modeled taking into account previous work. Simulation model calculates the axial and radial distribution of voidage, velocity, particle size distribution, pressure drop, gas emissions and temperat...

Acoustic Emission (AE) was used to study the fracture of oxide grown on mild steel. Samples were oxidised and mechanically deformed in air at 550 OC using strain rates of -and lo-' s-' in a bend test furnace having a ceramic 4-point bend jig. The results were compared with earlier observations made on oxides deformed at room temperature. In both cases equidistant cracks formed and the crack spa...

The numerical simulation of solid-gas two-phase flow is an important tool in the prediction of its flow behavior. Predicting the axial pressure profile is one of the major difficulties in modeling of solid-gas two-phase flow. A model using a Particle Based Approach (PBA) is developed to accurately predict the axial pressure profile in a vertical annular tube. The simulation model accounts for t...

The experimental procedures for obtaining importance-weighted k, values in clean and B.,C-poisoned ,LWHCR test lattices with different simulated moderator voidage states are described. The results of these measurements, presented as calculation/experiment values, are interpreted in two different ways, viz. in terms of the reactivity effect of BaC as control absorber and the effect of poison on ...

The influence of inert particles on liquid/solid mass transfer is studied in fluidized beds by using a binary-mixture of solids of differing size and density. The addition of inert particles of higher density and smaller diameter, e.g. glass beads, exerts remarkable effects on mass transfer coefficients in comparison to that of mono-component active particles at the same liquid velocity. The ex...
