Simulation of Auxin Accumulation and Transport in a Plant Root
Plant roots have an outstanding ability to grow in the direction of gravity or nutrients. Bending of the root tip in the preferred direction is achieved by asymmetric cell growth on the opposite sides of the root, dictated by asymmetrical distribution of the hormone auxin. Increase in ...

Oxygen Based Diffusion Modeling of Oxidation Behaviour of Encapsulated Lipids
Encapsulation is an established technique to protect sensitive materials from environmental factors such as oxygen and light. Nutritionally beneficial fatty acids like omega 3 fatty acids are susceptible to oxidation and are therefore encapsulated by drying an oil in water emulsion. It ... En savoir plus
CFD Investigation of a Photocatalytic Multi-Tube Reactor for Indoor Air Purification
In industrial countries, people spend most of their time indoors. Stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality [1]. Integration or retrofitting of a photocatalytic oxidation or PCO reactor into continuous flow ... En savoir plus
A Multi-physical Approach of a Sterilization System for Aseptic Food Processing
Sterilization is the process of deactivating microorganisms from a surface or a product. A high temperature gaseous mixture of hydrogen peroxide and steam became the accepted standard in most aseptic filling machines found in pharmaceutical, food and beverage industries [1, 2]. To ...

Hydrothemal Carbonization: A Renewable Alternative to Fossil Fuels and Respective Evaluation
Humanity is faced with an imminent energy crisis. The exponential growth of the human population and the consequential increase of the required energy on a global scale, the dramatic climate change and the exhaustibility of natural resources combined, force us to strive towards a ... En savoir plus
Modeling and Simulation of Hydrogen Generation in Membrane Reactor via Steam Octane Reforming
Various hydrocarbon compounds have been converted into pure hydrogen by using a catalyst and a palladium membrane in one reactor (PMR) in a one-step process where the reaction proceeds to almost complete conversion. Octane is converted into pure hydrogen using of a palladium membrane ... En savoir plus
A Flow and Transport Model for Low-Temperature Gaseous Nitrocarburizing of Stainless Steels
An integrated numeric, thermodynamic, and experimental analysis work was conducted to find out the proper flow and transport parameters of combined chemical species for low-temperature gaseous nitrocarburizing of stainless steels in an industrial furnace built for thermochemical ... En savoir plus
Reactive Transport Modeling of CO2 in Carbonate Rocks: Single Pore Model
Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the ... En savoir plus
Model Based Stimulus Experiments to Improve Biological Wastewater Treatment Performance
The municipal wastewater treatment in a sustainable context requires a smart technology in which an optimal combination of the ecological status and energy demand can be achieved. The integration of electron conductive materials into a traditionally constructed wetland (CW) has been ... En savoir plus
Predictive Model for UV Light Irradiation and PCO Reaction Kinetics in a Photocatalytic Reactor
A novel type of photocatalytic reactor, i.e. parallel flow tube reactor (PFTR) is presented for the degradation of indoor air pollution with UV-light. A Multiphysics model was developed in COMSOL Multiphysics® to predict the steady-state behavior under different inlet concentrations and ... En savoir plus
