Global trends and market pressures drive engineers to improve industrial equipment, rotating machinery and turbomachinery design, with a focus on delivering performance with improved energy efficiency, safety, durability and range with lower cost and time to market. To achieve targets, developers look at improving all aspects of machine performance.
Energy efficient rotating machinery reduce carbon emissions, but for thermal turbomachinery design engineers also must address emissions of NOx, SOx, unburned hydrocarbons and soot. As machines cycle more frequently, operate off-design, and burn multiple fuels, it becomes more difficult to meet emissions targets.

Reduce Fuel Burn, Increase Machine Efficiency
To reduce fuel burn or increase industrial equipment efficiency, developers look at all components and disciplines that could impact machine performance: turbine, compressor, combustor, inlet and exhaust as well as aero/hydrodynamics, thermal, combustion, mechanical and dynamics effects.
Improve Durability & Reliability
High firing temperatures can shorten product life; an appropriate thermal management strategy can mitigate detrimental effects.
Reduced carbon emissions call for higher machine efficiency, which often demands higher firing temperatures.
Broaden Machine Operating Range
The industrial equipment industry pushes turbomachinery to the limit. It must operate, both reliably and efficiently, over a wider operating range, with minimal performance degradation.
Compression and Gas Moving
Reducing power consumption is a pressing issue for providers of turbomachinery in automotive, chemical process, oil and gas, and HVAC applications. Efficient compressors, turbines, pumps and fans reduce power consumption and, hence, plant and building operating costs. Low maintenance translates to low operating costs consequently a focus on reliability.
Efficiency, operational flexibility and reliability are critical parameters for hydraulic machinery of all types. Hydraulic turbines must offer very high efficiency, and the equipment is now expected to operate over an increased operating range and to cycle more frequently. Requirements are similar for pumps, vehicle torque converters and marine liquid propulsion systems, including propellers.
Reducing fuel burn, for economic and operational reasons, is a key requirement for most aircraft engines, auxiliary power units, and gas and steam turbines. Low emissions, both carbon and non-carbon, satisfy growing public environmental concerns and increased government legislation.
Wind, Aircraft Propellers and Rotors
A key aerodynamic feature of wind turbines, aircraft propellers and rotors is the lack of flow guidance due to low blade solidity. Consequently, requirements include power delivery and aerodynamic efficiency over a broad range of flow incidence. Reliability and safety are also paramount due to inaccessibility and human safety considerations.
