A fractional-order ship power system: chaos and its dynamical properties

Karthikeyan Rajagopal et al.

Summary: The ship power system is studied using a fractional-order approach, with observation of a chaotic attractor and calculation of the fractional-order form using the Adam-Bashforth-Moulton method. Lyapunov exponents and bifurcation diagrams are analyzed, and a fractional-order controller is designed to remove chaotic dynamics, demonstrating its effectiveness through time plots simulation.

Entropy generation of tangent hyperbolic nanofluid flow over a circular cylinder in the presence of nonlinear Boussinesq approximation: a non-similar solution

H. Thameem Basha et al.

Summary: The study investigates the fluid transport characteristics and entropy generation of a tangent hyperbolic nanofluid over a horizontal circular cylinder with the influence of nonlinear Boussinesq approximation. The results show that nanofluid velocity increases with enhancing mixed convection parameter, isotherms thickness escalates with increasing radiation parameter, and total entropy generation rises for higher values of dimensionless temperature ratio parameter.

Entropy generation analysis in a microchannel Poiseuille flows of nanofluid with nanoparticles injection and variable properties

R. Lucky Monaledi et al.

Summary: In this study, a modified Buongiorno's nanofluid model was used to analyze the impact of nanoparticle injection and distribution on irreversibility in microchannel Poiseuille flow. Numerical solutions showed that nanoparticle aggregation towards the central region of the microchannel reduces skin friction and enhances heat transfer, while nanoparticle injection with Brownian motion decreases entropy generation rate.

Effectiveness of binary chemical reaction on magneto-fluid flow with Cattaneo-Christov heat flux model

S. R. R. Reddy et al.

Summary: The effect of binary chemical reaction on MHD Casson fluid flow over an exponentially stretching surface with Cattaneo-Christov heat flux was analyzed, along with the impact of modified Arrhenius activation energy. The study revealed differences in stretching velocity, reaction rate, wall temperature, and wall concentration based on specific exponential forms. Results showed that Newtonian fluid has higher temperature than non-Newtonian fluid, and increasing the magnetic field tends to decrease the flow of Newtonian/non-Newtonian fluids.

Karthikeyan Rajagopal et al.

Summary: This study investigates a modified FitzHugh-Nagumo neuron model with a sigmoid function-based recovery variable, coupled with electromagnetic flux. The dynamics of the proposed neuron model are examined, showing a decrease in the number of fixed points to one as the excitation current increases. Bifurcation plots are analyzed to demonstrate chaotic and periodic regimes for different excitation currents and parameters, with the construction of an N x N network for studying wave propagation and re-entry phenomena.

Controlling chaos and supressing chimeras in a fractional-order discrete phase-locked loop using impulse control*

Karthikeyan Rajagopal et al.

Summary: The study discusses the dynamical behavior of a fractional-order difference equation model of a third-order discrete phase-locked loop (FODPLL), proposing a simple impulse control algorithm to suppress chaos. A network of FODPLL oscillators is constructed and investigated for synchronization behavior, showing the existence of chimera states during the transition from an asynchronous to a synchronous state. The same impulse control method is then applied to a lattice array of FODPLL to synchronize chimera states.
