This research discusses an output voltage controller of the self-excited induction generator (SEIG). The SEIG is one part of the renewable energy application where it is not connected to the utility grid, but it uses the capacitor as an excitation source. One of the weaknesses of this generator is its voltage regulation caused by its load change. Thus, one method is needed to maintain its output voltage in a required voltage value. This research proposes a mathematical model of the SEIG and it is implemented using MATLAB SIMULINK. A capacitor arrangement based on PID controller is applied in t
The present study intends to elaborate on the heat generation/absorption of two-dimensional laminar nanofluid flow in view of the nonlinear stretching surface at a given surface temperature with partial slip effect. The influence of Joule heating and viscous dissipation are considered. For evolving mathematical formulation, a fundamental flow model based on boundary layer theory is done, which signifies mass conservation of momentum, energy, and concentration equations. The fundamental nonlinear PDEs are diminished to a couple of nonlinear ODEs by implementing the transformation technique. The
The study of non-Newtonian fluids has received a considerable and significant attention from engineers, scientists and medical mentors. In the current study, a mathematical framework has been developed to explore the physical properties of non-Newtonian Fluid Flow. Particularly, we aim to study the physical properties of a chemical reaction, and transfer of heat and mass features on magnetohydrodynamic flow of Casson fluid towards an extended permeable surface with non-Newtonian heating and viscous dissipation effect. The dimensionless regular system of ordinary differential equations (ODEs) h
The operational efficiency and long-term stability of spillway dam structures are critical for their safety and reliability worldwide. Dam failures can result from environmental conditions, aging, and unforeseen loads. Previous research has emphasized the importance of dam reliability, with numerical simulations playing a key role. Vibration analysis and fluid-structure interaction are integral to dam spillway reliability in this study. This comprehensive case study focuses on the Kenyir Dam spillway in Malaysia. The spillway designed as an uncontrolled chute spillway has experienced water-spi
The ability to monitor grain loss from a combine harvester during harvest is an important element in rice production to minimize grain loss. In this study, an experimental modal analysis was performed to evaluate the effect of the dynamic behavior of a stainless-steel plate at four different thicknesses to determine the desirable plate thickness for developing a sensitive plate for a grain-loss monitoring system. The plates were 250 mm long and 180 mm wide, and their respective thicknesses were 1, 1.5, 2, and 2.5 mm with each plate containing 78 measurement points. Modal analysis was performed
