New Functionality in Version 4.2a
- A new Slip Flow interface for modeling thermal and isothermal flows
within the slip flow regime. The Slip Flow interface makes it possible
to model the flow of the gas, including a thin layer of gas adjacent to
the walls (Knudsen layer), where the gas is significantly rarefied. The
Slip Flow interface is available in 2D and 3D.
- A new Transitional Flow interface, which you can use to model
isothermal flows across the full range of Knudsen numbers from the
laminar flow limit to the molecular flow limit. The Transitional Flow
interface is available in 2D.
- Knudsen’s Minium: This model, using the Transitional Flow
interface, shows that the flow rate of a rarefied gas between parallel
plates exhibits a minimum (Knudsen’s minimum) at a Knudsen number of
- Slip Flow Benchmark: A benchmark model of the flow between to
sealed chambers connected by a microchannel with conducting walls. This
model uses the Slip Flow interface.
