Issue Spotlight


December 2014

The December 2014 issue of the CJChE includes a collection of articles to celebrate the 65th birthday of Prof. J. B. Joshi. Prof. Joshi is known for his passion for bringing about a paradigm shift in the chemical equipment process design using advances in simulations and experiments that shed new insight on the turbulent, multiphase transport processes taking place inside process vessels. This issue offers contributions from his colleagues around the world as an acknowledgement of his impact on their own work and career.

November 2014

In the November 2014 issue of CJCE, the extraction of functional proteins from industrial broth has attracted interest lately as a way to overcome limited natural resources. In their article, Dadashi et al. developed a computational fluid dynamics model to describe the hydrodynamics and mass transfer phenomena taking place during continuous protein extraction from using a liquid-solid circulating fluidized bed (LSCFB) ion exchange system. They demonstrated that the model was a robust tool to simulate, scale up, and optimize the LSCFB ion exchange systems for protein extraction process.

October 2014

In the October 2014 issue of CJCE, Safronov et al. revisit a classical chemical engineering problem on the modelling of chemically reacting coal particles. One of the basic challenges in this system is the realistic modelling of transport properties in the gas phase and the coupling of the boundary conditions at the chemically reacting interface with the gas flow. The authors carried out a numerical study of the influence of the gas flow on heat and mass transfer in the boundary layer of a chemically reacting coal particle.

September 2014

The September 2014 issue of CJCE includes a section dedicated to the top papers presented in the 3rd International Symposium on Modelling of Exhaust-Gas After-Treatment (MODEGAT III). These papers reflect the symposium's purpose of promoting the exchange of state-of-the-art modelling and simulation techniques, fundamental mechanistic studies, experimental model validation and technical applications of modelling and simulation among researchers, scientists, and engineers from industry and academia.

August 2014

In the August 2014 issue of CJCE - we highlight the article by Dhaliwal and Guay who propose a set-based adaptive estimation technique for simultaneous state estimation and parameter identification of a class of continuous-time non-linear systems subject to time-varying disturbances. The method guarantees convergence of the parameter estimation error to zero and significantly determines the unknown state of the system with unknown bounded disturbance. The estimation and identification algorithms have been implemented to several simulation examples to demonstrate its effectiveness.

July 2014

In the July 2014 issue of CJCE - Polymer nanocomposites are novel materials that exhibit improved properties versus conventional microcomposites. There is increased interest in these materials as a good alternative to replace metals in many applications because of enhanced mechanical properties and processability, high conductivity and light weight. In their article, Sarvi et al. show that novel core-shell nanostructures of polyaniline-coated copper nanowires (PANI/Cu NWs) can be synthesised using a simple and reproducible approach by spontaneous chemisorption of PANI on copper surface.Please see Sarvi et al.

June 2014

In the June 2014 issue of CJChE – In their CFD special series article. Eskin et al. proposed a model to describe wax deposition in oil transport pipelines. They demonstrate how the deposit layer thickness and the mean deposit porosity are affected by the diffusivity exponent, the precipitation rate constant and the shear-removal factor. This manuscript brings us closer to the development of a global approach for accurate field-scale wax deposition forecasting.

May 2014

The May 2014 issue of CJChE features an article by Hadiseh Karimi and Kimberley B. McAuley about their development of an easy-to-use Approximate Expectation Maximization (AEM) method for estimating model parameters and disturbance intensities in Stochastic Differential Equation models. The main advantages of the proposed AEM method are that it is less computationally intensive than Markov Chain Monte Carlo methods and that it does not require linearization of the model equations.

April 2014

In the April 2014 issue, we highlight "Pumping Characterisation of the Maxblend Impeller for Newtonian and Strongly Non-Newtonian Fluids," by Vincent Stobiac, Louis Fradette, Philippe A. Tanguy and Francois Bertrand.

This paper examines the pumping mechanisms generated by the Maxblend impeller. Lattice Boltzmann Method (LBM) results are first compared to previously published Finite Element Method (FEM) data. These results are next used to revisit and better understand recent experimental data based on 2D particle image velocimetry (PIV) and the decolourisation method. No such extended numerical investigation of the pumping capacity of the Maxblend has been done for Newtonian and strongly non-Newtonian fluids.

March 2014

In the March 2014 issue, Joshi et al. review of the literature pertaining to Petroleum Coke (petcoke) Gasification following a thematic framework so that the information is available at a glance and is expected to be useful as a single point source to the researchers and practicing refiners. This is a timely review because the production of petcoke in refineries is progressively peaking up due to the trend of processing heavy crudes and in a renewed interest in delayed coking process.

February 2014

In the February 2014 issue of the CJChE, Janssen and Hoogland review emulsification modelling techniques in industrial practice, based on their experience with food and personal care emulsions in Unilever.

January 2014

The January 2014 issue highlights the next article in the CFD special series where Kartushinsky et al. investigate the deposition of aluminium oxide particles onto a horizontal flat plate within the laminar boundary layer in the free-stream moderate turbulent flow. The obtained numerical results show that the deposition process is determined both by the hydrodynamics of streamlining of the plate surface and the elastic and adhesive properties of the particles and the surface.
