High-Performance Aerodynamic Design of a Gas Turbine Exhaust Diffuser Leveraging CFD-Based Entropy Map

Sunday, June 25, 2017
8:00 am – 5:00 pm

Gas turbine exhaust diffusers play an important role in turbine power output by increasing the pressure ratio across the last stage turbine by making the turbine exit static pressure sub-ambient.  The main aerodynamic design goal of an exhaust diffuser is to obtain maximum recovery in static pressure with various design constraints of intervening struts for bearing support and service lines and duct length available for flow diffusion, including the design-to-cost objective.  While the diffuser design focuses on realizing an efficient diffusion in the front and mid-section, in the aft section, the design objective shifts to obtaining a more uniform velocity distribution to meet the requirements at the inlet to Heat Recovery Steam Generator (HRSG) in a combined-cycle operation.

Ideal diffusers are characterized by uniform axial velocities with no swirl at both inlet and exit and with no loss in total pressure across the diffuser. Cp (static pressure rise coefficient), which is defined as the rise in static pressure from diffuser inlet to exit divided by the dynamic pressure (the total pressure minus the static pressure) at the inlet, is generally used to assess the diffuser aerodynamic performance. Actual diffusers in gas turbines, however, often have non-uniform profiles of all three velocity components, pressure, and temperature at both inlet and outlet. These non-uniformities present a special challenge in calculating Cp for diffuser performance assessment. CFD-based entropy map can be used to delineate diffuser flow zones for design improvement.

Uncertainty Quantification and Turbomachinery

Sunday, June 25, 2017
8:0 a.m. – 5:00 p.m.

The field of Uncertainty Quantification is evolving rapidly and becoming more and more important for turbo machinery predictions, because of the ever increasing sophistication of the computational models used for turbomachinery design. Cavity modeling, advanced description of turbulence (hybrid RANS-LES models, SAS models, etc.), real gases equations of state and in general complex thermodynamic models are just some examples of the increased complexity of the computational models used for turbomachines, in the quest to increase the accuracy and applicability of these models to different industrial applications. As the complexity and the scale of the models grows, the need to quantify the effect of uncertainties due to input variability, model calibration, model form uncertainty, numerical errors and so on becomes more and more important.

In this context, the module will cover different UQ techniques such as Monte Carlo with Metamodels (stochastic collocation), Non-Intrusive Polynomial Chaos and their impact on turbo machinery design. The module will provide examples where different techniques are compared and an example of Gaussian Process Regression will be shown. Industrial applications such as reliability of gas turbine blades, manufacturing-induced variability of centrifugal compressors performance and inference from experimental data of wind turbines power output will be shown.  Participants are requested to bring a laptop.

Who Should Attend
MSc, Phd, Design Engineers, and Academics involved with Turbomachinery Design or Analysis. UQ is becoming a key topic in CFD for turbomachinery.

8:00 a.m. – 5:00 p.m.

The ISO 55000 Standard for Asset Management was released in January 2014.  It is now being implemented through industry best practice and regulation in Australia, Canada, the UK and countries in the Europe Union.  In the US, PG&E has certified to this standard and many utilities in North America are presently considering its implementation.

ISO 55000 is a Management Systems Standard focused on extracting maximum value from assets over their entire life cycle. It requires comprehensive risk-based planning for asset and related system requisitions as well as optimal operation, maintenance and continuous improvement of all assets – material and human.  It provides a sustainable framework for asset managers and service providers in many business sectors. It fits well with other management systems standards such as ISO 9000 and ISO 14000 and can be implemented in stages to fit the organization's needs.

This workshop will introduce the Asset Management Standard with a Descriptions of its Principles and Examples of its Application through Individual Case Studies coupled with Interactive Exercises. The Instructors are Members of the ISO 55000 Standards Committee and authors of significant portions of the present Standard.

Why Attend?
Asset Management involves the Proper Disposition of ALL Resources over the Duration of a Business Project. It encompasses the coordinated and optimized planning, asset selection, acquisition/development, utilization, maintenance and ultimate disposal or renewal of individual assets and systems.

ISO 55000 – the Asset Management Standard – is akin to the existent ISO 9000 – Quality Management Standard and ISO 14000 – the Environmental Management Standard. It is in the early stages of Utilization. Given the Universal Application of ISO 9K and ISO 14K,  ASME will be a leader in presenting ISO 55K Principles to Practicing Engineers AND Engineering Students.

Gas Turbine Aerothermodynamics and Performance Calculations

Sunday, June 25, 2017
8:00 am – 5:00 pm

This interactive workshop provides review and reinforcement of relevant thermodynamic and aerodynamic concepts as applied to gas turbine engines, and introduces performance calculation methods of both aircraft engine and power generation gas turbines. The workshop emphasizes fundamentals which will be helpful for the practicing engineer but is not designed to review industrial practices which are usually proprietary. The acquired knowledge, including the review of illustrative examples, will enhance the participants' ability to excel in various assignments in gas turbine design, development, education, and application. The workshop material has been evaluated by the Department of Mechanical and Aerospace Engineering of North Carolina State University.

The workshop includes: a review of the relevant thermodynamics and compressible flow; introduction to cycle analysis; propulsive, thermal, and overall efficiencies; elements of turbomachinery aero design;
familiarization with combustor characteristics; integration of component performances to obtain overall
engine performance with illustrative examples of design point and off-design calculations; multivariable
solver; and various cycles used for power generation.

After completing the course the participants should be able to apply aerothermodynamic concepts to the analysis of gas turbine engines; analyze turbomachinery velocity diagrams and relate those to
thermodynamic parameters; appreciate the usefulness of the degree of reaction and the radial equilibrium equation; comprehend the discipline of operability and combustor characteristics; analyze cycle analysis problems on integrating the component performances to get the overall engine performance. The illustrative examples on the integration of the component performances to obtain the overall performance will facilitate comprehension of compressor/turbine matching; accounting for turbine cooling flows; the method of sizing critical flow path areas at the design point; method of satisfying conservation laws to achieve cycle balance at off-design; technique of the multivariable solver used in cycle models; making models match test data; and the analysis of various engine cycles in the power generation field including hybrid cycles.
