Center of Engineering and Multiscale modeling of Fluid flow
Excess, unrecoverable hydrocarbons are collected and burnt (in a flare) before releasing to atmosphere to reduce their environmental impact. Millions tones of hydrocarbons are burnt each year all around the world. A survey shows that, in 2017, around 270 million tones of CO2 is emitted by flaring. In many industrial…
You see an OpenFOAM simulation of a single phase stirred tank reactor using AMI technique. This simulation is performed to find the residence time distribution (RTD) in a stirred tank reactor. In the design and scale-up of chemical reactors, the residence time distribution of fluid particles inside the reactor should…
In many occasion in process industries (i.e. chemical engineering), we need to create a random packed bed of Catalysts. Packing of Hollow Cylinders in reactor (heterogeneous catalytic reaction) tubes can be simulated using DEM. This packing will then be used in other reactor flow simulations for more detailed kinetics, heat…
Many industrial processes like granulation, particle coating, bio-mass pyrolysis, dryers contain rotating drum as a part of their processes. its rotation cause a gentle motion of particles. So, this gentle motion brings particle to the bed surface, where particles avalanche from top to bottom. The drum wall pulls particles up…
Screw conveyor uses the power of a rotating helical ribbon to transport solids from one place to another. They usually are horizontal or with a slight angle with respect to horizon. They have applications in many industries including chemical and petrochemical, power plants, cements, paper, flour, iron and steel foundries,…
Bubble columns are useful processing units to contact gas and liquid for inter-phase mass transfer and chemical reactions. They have been applied in chemical, biomedical, pharmaceutical, petrochemical, waste-water treatment and other industries. Their construction is simple: a vertical column filled with liquid (mostly water) and a gas entering from bottom…
V-blender (V-mixer) is found in most of solid processing industries. They provide reliable and easy mixing of dry powders in batch mode. This mixer can be found in many industries such as food and pharmaceutical processing. You see a list of V-blender applications here: Food processing : mixing of dairy…
Gas solid fluidized bed is the most common solid-gas contractors in many processes like reactions, drying, coating and size separation. The unique heat & mass transfer capabilities between phases and robust mixing make fluidized bed a good candidate for many gas-solid processing units. In practical applications, they can operate in…
