Hydromechanics, Aerodynamics and Thermodynamics: Critical Numerical Analysis of Aerodynamics of BLE Turbine Blade

Abstract

This contribution presents a numerical analysis based on the effects of aerodynamics of the bump-based humpback whale fins available on the turbine blade edge. In this research, performance comparisons have been made based on dual sequestered blades. One of the blades was sinusoidal in shaped with Bumped Lead Edge (BLE) and the other one with Upright Leading Edge (ULE). However, all the blades are based on a similar cross-sectional profile i.e. NACA-012. This research has been based on simulations of Reynold’s number i.e. 1.8.105 of Attack Angle (AA) i.e. from ‘0º - 30º’. At this angle, especially greater than 10º, the BLE has indicated an enhancement in about 3.5% to 9.0% lift and a reducing drag whereas the negligible variation in lifts and minor drag is displayed for AA less than 10º. The findings in this result for BLE have indicated a substantial achievement in aerodynamic features for particular AA.

An Assessment of Data Transmission Reliability in Mobile Wireless Sensor Networks

“…Methods such as calculating the likelihood of route buffer overflows are used to gauge congestion in the network, and the ratio of obtained packets at the receiver end to those sent from the senders' end may be used to demonstrate the network's overall reliability. The three forms of network dependability evaluation illustrated above (capacity reliability, performance reliability, and connectivity reliability) [25] can reflect different requirement of functionalities, network performance and metric ranges, but it is still problematic to determine the complete capacity of the system whereas it is undertaking a specific task.…”
