New App: Mixer
The purpose of the Mixer application is to provide a user-friendly interface where scientists, process designers, and process engineers can investigate the influence that vessels, impellers, baffles, and operating conditions have on the mixing efficiency and the power that is required to drive the impellers. You can use the app to understand and optimize the design and operation of a mixer for a given fluid.
You can specify the dimensions of the vessel, from a list of three types; and the dimensions and configuration of the impellers, from a list of eleven types. The vessels can also be equipped with baffles. You can further specify the properties of the fluid that is being mixed as well as the impeller speed.

New Rotating Machinery, Non-Isothermal Flow Interfaces: "Turbulent Flow, Algebraic yPlus" and "Turbulent Flow, L-VEL"
Using the Turbulent Flow, Algebraic yPlus and Turbulent Flow, L-VEL turbulence models in nonisothermal, rotating flow simulations leads to faster and more robust convergence. In many cases, the level of accuracy obtained with these models may be adequate for the application at hand. In other cases, they may provide general guidelines for the design of mixers and processes. A more accurate transport-equation turbulence model may be needed for quantitative analyses.
