Over the past two years the Australian biodiesel industry has faced difficult times causing large scale producers to drastically curtail production with some even ceasing operation. This turn of events has highlighted the advantages of small scale production, which are investigated in depth in a companion paper (de Boer and Bahri 2009a). For small scale production to be viable the transesterifi...

Mathematical models have been popularly applied to study the compression processes of superheated refrigerant vapor in compressors. As to the case when refrigerant enters a compressor cylinder in the state of liquid and vapor mixture, however, the availability of fundamental studies is very limited. -A mathematical model is presented to simulate the compression processes of two-phase saturated ...

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...

The authors develop a minimal multiscale lattice model of the binary mixture saturated lipid and cholesterol that reveals new thermodynamic mechanism behind appearance heterogeneous liquid ordered domains in mixture.
