Flow pattern transition in liquid-liquid flows with a transverse cylinder
Abstract The effect of a cylindrical bluff body on the interface characteristics of stratified two-phase, oil-water, pipe flows is experimentally investigated with high speed Particle Image Velocimetry (PIV). The motivation was to study the...

A comprehensive kinetic model for Cu catalyzed liquid phase glycerol hydrogenolysis
Abstract Hydrogenolysis of biomass-derived glycerol has been investigated as an alternative route for the production of value-added chemicals, such as 1,2-propanediol, also commonly denoted as propylene glycol (PG). Intrinsic glycerol hydrogenolysis ...

Heat loss prediction of a confined premixed jet flame using a conjugate heat transfer approach
Abstract The presented work addresses the investigation of the heat loss of a confined turbulent jet flame in a lab-scale combustor using a conjugate-heat transfer approach and large-eddy simulation. The analysis includes the assessment of the...

Experimentally validated numerical study of gas-solid vortex unit hydrodynamics
Abstract A three-dimensional numerical analysis of the flow in a Gas-Solid Vortex Unit (GSVU) is carried out. The numerical model is first validated by comparing the bed pressure drop and solids velocity with experimental data. Next, the influence...

Generic flow sheet model for early inventory estimates of industrial microbial processes. I. Flowsheet development, microbial growth and product formation
Abstract Early stage process analysis to maximize economic feasibility and minimize environmental burden is critically important for process flow sheet selection and optimization. This is equally true for bioprocesses. For many systems, including...

Fouling mitigation on a woven fibre microfiltration membrane for the treatment of raw water
Abstract The main source of drinking water in rural areas of South Africa is surface water. Improving drinking water and sanitation facilities alone does not completely solve the problem of waterborne diseases. A novel simple gravity driven...

The influence of cetomacrogol ointment processing on structure: A definitive screening design
Abstract Batch-to-batch variability is a challenge for the industrial scale production of ointments. Therefore the current investigation focussed on identifying and understanding critical process parameters (CPPs) for cetomacrogol ointment. This was ...

A novel methodology to study polymodal particle size distributions produced during continuous wet granulation
Abstract It is important during powder granulation to obtain particles of a homogeneous size especially in critical situations such as pharmaceutical manufacture. To date, homogeneity of particle size distribution has been defined by the use of the...

Design of an embedded inverse-feedforward biomolecular tracking controller for enzymatic reaction processes
Abstract Feedback control is widely used in chemical engineering to improve the performance and robustness of chemical processes. Feedback controllers require a ‘subtractor’ that is able to compute the error between the process output and the...
