Tubular Reactor with Nonisothermal Cooling Jacket

This example uses the Transport of Diluted Species and Heat Transfer in Fluids interfaces as available in the COMSOL Multiphysics base package to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor also uses a cooling jacket with a nonisothermal coolant temperature. The coolant is modeled with a ...

Submodeling Analysis of a Shaft - new

This model shows how to perform a submodeling analysis in order to evaluate structural stress. Using a submodel helps to compute the results in a refined geometry detail while applying loads and constraints in the global model.

Traveling Load - new

This example shows how to model a load which varies in space and time. A series of load pulses travel along a beam which is supported at equal distances. For some combinations of the traveling speed of the load pulses and the spacing between them, it is possible to excite resonances in the beam. The effects of four different combinations of these parameters are investigated.

Beam Subjected to Traveling Load - new

This application simulates the transient response of a beam that is placed on several equidistant supports and is subjected to a traveling load. The purpose of the application is to analyze the response of the bridge when vehicles pass over the same. It is observed that for a bridge with given geometric and material properties, certain vehicular speeds cause resonance in the bridge and it ...
