COMSOL Multiphysics® Model of an Industrial Top-Fired Steam Methane Reforming Reactor
Figure 1 shows a simplified scheme of a typical industrial steam methane reforming (SMR) reactor, which is a top-fired, packed-bed multi-tubular chemical reactor, consisting of a series of catalytic tubes arranged within a furnace. The tubes contain two adjacent catalytic sections filled ... Read More
Contact Resistance and Joule Heating
Simulation of thermal and electrical contact resistance of welding torch nozzles In modern engineering and scientific research, accurate modeling of contact resistances, both electrical and thermal, plays a crucial role in the design and analysis of technical systems. Our project ... Read More
Convective Heat and Moisture Transfer Modelling in Porous Insulation for Large Thermal Storage
In view of an energy system based on fluctuating renewable sources, the use of thermal energy storage (TES) systems plays a crucial role. In particular, large-scale underground water-based TES represent a promising solution as demonstrated by a number of cases currently being established ... Read More
Copper Corrosion Mechanisms by Simulation and Experiment Using Small Test Structures
Product lifetime prediction is a crucial task in microelectronics design and fabrication. Understanding of the underlying processes causing material degradation and product failure is essential for establishing accurate lifetime models. This work aims to investigate and model the ... Read More
Degassing of PP Pellets in a Silo: Keeping C9 Concentrations Below the Lower Explosion Limit
When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... Read More
Design and Simulation of an Additive Manufactured Microwave Cavity for Compact Cold Atom Clocks
We present the design and performance simulations for a microwave cavity for use in novel compact cold atom atomic clocks. Design goals for such a microwave cavity are a resonance frequency at the Rubidium ground-state transition frequency of 6.835 GHz, combined with a moderate quality ... Read More
Design and Simulation of Bragg Grating Based Optomechanical Sensor for Atomic Force Microscopy
Atomic force microscopy (AFM) has been widely recognized as an essential tool that enables the imaging of surface, measuring and localizing many different forces and becoming a standard technique for force spectroscopy at the nanoscale. While conventional AFM is well-developed, recent ... Read More
