Penelitian ini membahas tentang analisis kecepatan dan temperatur di sekitar titik stagnasi terendah pada magnetohidrodinamika fluida nano yang melewati silinder berpori. Persamaan pembangun diperoleh dari persamaan dimensional, yaitu kontinuitas, momentum, energi. dimensional tersebut kemudian ditransformasikan menjadi nondimensional menggunakan parameter-parameter variable-variabel nondimensi...

In this paper, mixed convection of ferrofluid containing magnetite, Fe3O4 with ferroparticles suspended in water at the lower stagnation point on a horizontal circular cylinder is investigated. The partial differential equation which derived from transformation dimensional governing and non-similarity consideration effect magnetohydrodynamic (MHD) are solved numerically by using Keller-box meth...

The present study is about the numerical analysis of Casson fluid’s boundary layer slip flow beneath impact suction/blowing past a permeable cylinder stretching exponentially. modeled partial differential equations are transformed to nonlinear ordinary by applying appropriate transformation. Keller box procedure, tool famous for its achievements, used. relevant physical parameters like suction,...

This research is a natural continuation of the recent paper “Exact solutions of the simplified Keller–Segel model” (Commun Nonlinear Sci Numer Simulat 2013, 18, 2960–2971). It is shown that a (1+2)-dimensional Keller–Segel type system is invariant with respect infinite-dimensional Lie algebra. All possible maximal algebras of invariance of the Neumann boundary value problems based on the Keller...

An unsteady mixed convection flow of Williamson nanofluid over a stretchable surface embedded in porous medium is scrutinized numerically. Here the characterized by Darcy Forchheimer model under influence magnetic field. Heat transfer analysis with two different conditions namely, prescribed temperature (PST) and heat flux (PHF) are taken into account. The evolved mathematical numerically solve...

We study a continuous-time game of strategic experimentation in which the players try to assess the failure rate of some new equipment or technology. Breakdowns occur at the jump times of a Poisson process whose unknown intensity is either high or low. In marked contrast to existing models, we find that the cooperative value function does not exhibit smooth pasting at the efficient cut-off beli...
