Axstream Improves Turbomachinery Design Lessons

The Kaluga branch of the Bauman Moscow State Technical University has adopted Softinway's Axstream software to assist in teaching turbomachinery design. The university and Softinway signed a software licence agreement according to which the educational version of Axstream will be incorporated into the curriculum, helping students to gain a real-life understanding of the basic principles of turbine/compressor design. Axstream Educational Version is intended for design and optimisation for four types of machines: axial turbines, axial compressors, radial turbines and radial compressors.

It consists of modules for preliminary design, 1D/2D analysis, flow-path multidisciplinary optimisation, airfoil profiling, 3D blade stacking and 3D finite element analysis/computational fluid dynamics (FEA/CFD) analysis. Dr Jinov Andrey Alexandrovich, professor of mechanical engineering in the Kaluga branch, said: 'One of the key points while teaching turbomachinery design is to show students how preliminary design is performed - first for one-stage and then for multi-stage flow paths.

'And here Axstream will be helpful for us, since its preliminary design module allows the setting of many important parameters that influence the efficiency, manufacturing cost and reliability of the final design, such as the number of stages, diameters, blades heights and cascades, metal angles, reactions of future flow path, etc.

'Using Axstream features for airfoil cross-section profiling, it is easier to explain to students how to find suitable airfoil outline on the base of flow calculations in planar profile cascades, with regard to boundary layer and compressibility effects. 'Finally, Axstream is a very usable tool while providing students with an in-depth insight into 3D blade design,' added Alexandrovich.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
