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 ...

iCP Apps to Readily Solve Reactive Transport Simulations in COMSOL Multiphysics®
Reactive transport models (RTM) that couple physical and chemical processes are commonly used to solve a large variety of problems in the environmental industry. There are a series of codes designed to solve this kind of problems. However, their use requires typically much effort due to ... En savoir plus
CFD Investigation of Cross Bubbly Flow through a Bubble Column with Rectangular Geometry
Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, ... En savoir plus
Coupled Optical & Thermal Model of a Silicon Microprobe
The topic of my work is modeling of a multimodal waveguide microprobe which is suitable for deep brain infrared stimulation. The goal of the research is the investigation of the therapeutic effect of optical IR excitation on biological active substances. In the physical model I ... En savoir plus
Multiphysical Simulation of Moved Data Cable
In general this thesis is about the effects of mechanical stress on data cables in moved applications. If a data cable is loaded with different kind of forces and used within high frequency applications it is possible, that the geometrical changes may have an impact on the electrical ...

Keep it Simple and Learn More - On a Stationary Study of a Time-Dependent Problem
Today’s driver hardware for High-intensity discharge (HID) lamps is bulky, expensive and not particularly energy-efficient. A downscaling of the devices seems possible by increasing the operation frequency from typically 400 Hz to some hundred kilohertz. However, efforts to design high ... En savoir plus
Impact of the Forces due to CLIQ Discharges on the New HL-LHC Beam Screen
In the framework of the high luminosity large hadron collider (HL-LHC) project, important upgrades will take place by 2024 including the installation of new superconducting magnets in which new beam screens will be placed. The beam screen is an octagonally shaped pipe inserted into the ... 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
Dynamic Simulation of a Coaxial Magnetic Gear Using Global ODE's and the Rotating Machinery, Magnetic Interface
The coaxial magnetic gear is a good alternative to classic mechanical gears. The magnetic gear has high mechanical durability, overload protection and lower noise, than a mechanical gear [1,2]. A static model of a magnetic gear [3,4] is used for simulation of the magnetic fields and ... En savoir plus
Simulation and Visualisation of Shielding Gas Flows During Wire-Arc Additive Manufacture
One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... En savoir plus
