TurboTides V. 4.7.18 Release Notes

TurboTides is an integrated design system that allows designers to conduct turbomachinery design on a single platform. The system supports design and analysis of axial and radial compressors, turbines, pump and fans. This powerful program distinguishes itself from its peers with unique features such as calibrated 1D models through data reduction, easy CAD import and parameterization, embedded optimization and interactive database that facilitates reuse of the past designs.

We are proud to present you some highlighted features in this 2019 TurboTides release v.4.7.18.

1Cycle module:

1. Supports the design and analysis of the following thermodynamic cycles and configurations:

a. Rankine cycle, including Organic Rankine Cycle (ORC)

b. Gas turbine cycle

c. Super-critical CO2 cycle

d. Refrigeration cycle

e. Turbocharger matching

f. Multistage compressor, including Integral Gear Compressor (IGC)

2. In design mode, the cycle solver allows preliminary sizing of the compressor or turbine by invoking the 1D solver, which not only makes the prediction of cycle performance more accurate, but also produces the preliminary designs for the compressors/turbines.

3. In analysis mode, the cycle performance can be analyzed based on the component models. Multiple point analysis allows the user to conduct parametric study of a series parameters.

4. All component models, including compressor, turbine, heat exchanger, engine and pipe can be configured conveniently to support cycle analysis.
