The TurboTides Concept

TurboTides was developed by an expert global team with decades working in the turbomachinery industry. TurboTides is not only a highly integrated, interdisciplinary, groundbreaking CAE package for turbomachinery design, but also a powerful platform to digitize and manage the cumulative design experience, knowledge, resources and other intellectual property of turbomachinery manufacturers.

TurboTides provides an advanced R&D platform to achieve the goal of standardizing the design process and supporting the reuse and full exploitation of current and past designs. TurboTides accomplishes this through a unique combination of fully parametric design, turbomachinery-specific data storage and retrieval, direct design methods and multidisciplinary design optimization, all within a single, fully integrated package.

Design System Integration

TurboTides is a new software that takes full advantage of the latest and most modern engineering and software development tools and practices so that it provides a highly integrated, all-in-one R&D platform. All key functions for turbomachinery design are fully integrated into the TurboTides platform, including:

◆ Cycle Analysis

◆ 1D Meanline Design and Performance Prediction

◆ 2D Throughflow and Blade-to-Blade Analysis

◆ 3D Geometry Generation and Blade Shaping

◆ CAD Import and Export Interfaces

◆ 3D CFD with Automatic Grid Generation

◆ 3D FEA for stress, thermal, and modal analysis

◆ Multi-level and multi-disciplinary optimization

◆ Knowledgebase Management

Design Process Standardization

TurboTides provides an interdisciplinary workflow management system that enables a standardized design process. By considering aerodynamic performance, mechanical design, and manufacturing at each stage of the design process, potential issues can be addressed as early as possible in each design project. 

TurboTides allows manufacturers both to standardize their design process and include multi-level optimization (from cycle, 1D, 2D, to 3D) to reduce design time, improve the design success rate, and improve the performance of their turbomachinery designs.

Design Knowledge Customization

There are various turbomachinery design models and methods for different types and applications. TurboTides allows users to apply different customizable design rules and knowledge to different applications. TurboTides offers specific design models and tools for gas turbines, turbochargers, ORC, super-critical CO2 compressors and expanders, refrigeration and heat pump compressors, process compressors, turbo expanders , centrifugal pumps, etc. Meanwhile, TurboTides offers services to customize the design system to user’s special needs, such as specific reports or a customized work flow.

Design Experience Digitization

The accumulation of design experience is essential for the long-term health any advanced turbomachinery manufacturer. TurboTides provides a powerful system for design experience digitization and technology management that has not previously been available to the turbomachinery industry.

With TurboTides, users can utilize proven design methods to mitigate design risks and shorten design phases. Find an existing design that is close to what is needed, for example, and do a shroud cut or radius trim to fit the new conditions.  Use the advanced reverse-engineering tools to import past designs into the design knowledgebase whether they were designed in TurboTides or not. 

TurboTides provides UDF (User-Defined Functions) for user’s innovations; and helps users to digitize and manage design knowledge.

Along with the preserving your organizational knowledge of turbomachinery design, TurboTides will enable the future development and application of machine learning and AI design capabilities to your turbomachinery designs.
