This example studies heat transfer in a composite two-dimensional structure. Four materials with distinct thermal conductivities k compose the structure. The top and bottom boundaries are facing environments respectively at 0°C and 20°C. The temperature distribution and the heat flux ... Read More
This tutorial model illustrates the use of the nucleate boiling heat flux features to compute the transient cooling of a cylindrical rod plated with nickel, and immersed in a pool of boiling water. The temperature and heat flux results obtained with a 3D time-dependent computation, with ... Read More
A lab-on-a-chip platform can be realized on a rotating disc by designing channels and other features to use the Coriolis or centrifugal forces to manipulate the flow. These forces are controlled by changing the angular velocity of the disc, so the platform is programmed by using a ... Read More
This model simulates the mixing of two types of grains in a rotating drum with baffles. The effect of the number of baffles on the mixing is demonstrated by varying the number of baffles in the drum. This model also demonstrates how to build and run a model method that evaluates the ... Read More
This example uses the Granular Flow interface to model the formation of the grain heap and then its subsequent spreading using a cylindrical roller. The roller has a combined rotational and translational motion. The resulting powder bed is then analyzed to determine its quality based on ... Read More
This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... Read More
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Surfaces. In this model, three layered shells are connected to heat domains by interior and exterior boundaries. The results obtained with the Heat Transfer in Shells ... Read More
This model shows how to define a frequency-domain analysis of heat transfer. The 3-omega method uses the Cahill's equation to approximate the thermal conductivity of a sample from the measured temperature of a metal strip placed on top of it and subject to oscillating heating. The 2D ... Read More
This tutorial model compares the results between a domain approach and the Thin Moisture Barrier feature to simulate the moisture transport in a wall with a vapor barrier. The Thin Moisture Barrier feature neglects diffusion, two studies are proposed, a first one where diffusion is ... Read More
Commercial heat exchangers often feature a complex design. It is significantly easier to build a design with new CAD parameters than to build designs with novel topologies. This model demonstrate how to optimize the size and position of the tubes in a tube and shell heat exchanger. It is ... Read More
