A hybrid computing scheme has been developed in the paper, which uses CFD softwares: Gambit for mesh generation, Fluent for carrying out hydrodynamic analysis, and employs a Genetic Algorithm (GA) for optimisation. It has been utilised to solve optimisation problems related to thermo-fluid field in a fully automated way by using specific system commands. In the developed hybrid computing scheme, the GA and CFD softwares combine each other seamlessly and data transfer takes places without any manual intervention. In this study, the main challenge lies in embedding highly structured commercial softwares, like Fluent and Gambit, inside an indigenously developed hybrid computing scheme. Using the said hybrid computing scheme, two different methodologies have been adopted to optimise the shapes of 2D symmetric nozzle. Corresponding to the optimised shapes of the nozzle, streamline patterns have been developed and variations in pressure loss (PL) factor values have been studied.

Ultrasonic wind sensor for smart wind turbine control - Polaris / USA - Case Study
The American wind turbine manufacturer Polaris trusts for their wind turbine applications anemometers from Lufft. Over 50 wind turbines have already been equipped with our ultrasonic anemometers Ventus-UMB and V200A-UMB. Crucial in these applications is a high degree of precision and a long, maintenance-free useful life. In addition, controlling of the turbine complex requires a high frequency of data to provide the most efficiency. Our Ventus-UMB and V200A-UMB anemometers perform all this.

Kinetic characterization, thermo-stability and Reactive Red 195A dye detoxifying properties of ...
An indigenous and industrially important manganese peroxidase (MnP) was isolated from solid-state bio-processing of wheat bran by white-rot fungal strain Ganoderma lucidum IBL-05 under pre-optimized growth conditions. Crude MnP extract was partially purified (2.34-fold) to apparent homogeneity by ammonium sulphate precipitation and dialysis. The homogeneous enzyme preparation was encapsulated on gelatin matrix using glutaraldehyde as a cross-linking agent. Optimal conditions for highest immobilization (82.5%)...
Steam Turbine Rotor Transient Thermo-Structural Analysis and Lifetime Prediction
Market requirements for faster and more frequent power unit start-up events result in a much faster deterioration of equipment, and a shorter equipment lifespan. Significant heat exchange occurs between steam and turbine rotors during the start-up process and even more intensive heat exchange takes place during the condensation phase in cold start-up mode, which leads to further thermal stresses and lifetime reduction. Therefore, the accuracy of lifetime prediction is strongly affected and dependent on the...
