Effect of Different Parameters on Energy Loss Coefficient of Square Edged Orifice Plate
Abstract: Orifice meter is a differential pressure type flow measuring device in which energy loss is a major problem. The energy loss coefficient is an important indicator of energy dissipation. In this paper, different parameters like contraction ratio, orifice plate thickness and Reynolds number were analyzed by numerical simulations using Ansys CFX 15.0 software for their effects on energy dissipation. Results of simulations revealed that, Reynolds number has negligible effect on …

ENERGY LOSSES IN FLOATING OFFSHORE WIND TURBINE WITH VARIABLE WIND DIRECTION
Abstract: The paper analyses the effects of the variation of wind direction onto the performance of a floating offshore wind turbine (FOWT). The evolution of the Cp coefficient is developed as a function of the velocity of the yaw angle correction when realigning the FOWT after a wind direction change. The results are computed for velocities correction of the yaw angle between 1º/min and 5º/min. A maximum drop of the Cp …

Dynamic Vibration and Damping Analysis of Sustainable Nano-Reinforced Polymer Composite Elements for Vehicle Suspension Applications
Abstract: This paper presents an analytical investigation into the dynamic vibration characteristics of nano-reinforced polymer composite elements intended for vehicle suspension applications. A single-degree-of-freedom (SDOF) quarter-car model is employed to derive fundamental expressions for natural frequency, damping ratio, logarithmic decrement, and displacement transmissibility. The primary contribution lies in establishing explicit analytical linkages between material-level viscoelastic properties specifically storage modulus and loss modulus and system-level suspension parameters including stiffness and damping coefficients. …

Wave Effects on the Performance of Giant Floating Offshore Wind Turbines
Abstract: The performance of a giant floating offshore wind turbine under the effects of wave misalignment has been modelled and simulated. Heave and period of the sea waves have been considered as the most relevant parameters to determine their effects on the power generation of the floating offshore wind turbine. The simulation has been run for two different situations, a non-restriction tilt angle case and a limited tilt angle case. The …

Experimental Analysis of Wear Characteristics in Natural Fibre Composite Materials
Abstract: In mechanical systems, energy loss and material degradation due to attrition are frequently the consequences of sliding contacts, which frequently lead to premature system failure. In this study, at 50°C, 80°C, and 110°C, the hardness was tested; the results showed that the values were 350.7, 422.5, and 455.5 HV, respectively. After conducting a high-temperature wear test, the mass loss of the as-deposited composite coatings was assessed by an electrochemical approach …

Seismic-Resilient Structural Systems: Geotechnical Engineering
Abstract: Earthquakes represent one of the most destructive natural hazards, capable of causing severe structural damage, loss of life, and substantial economic disruption. Seismic waves propagating through the ground can induce excessive forces and deformations in buildings, often leading to partial or complete collapse. Statistical records indicate that thousands of earthquakes occur globally each year, including several major events that result in significant damage. Past earthquake disasters have repeatedly demonstrated that …
