Abstract

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 persamaan kontinuitas, momentum, dan energi. Persamaan dimensional yang diperoleh kemudian akan ditransformasikan menjadi persamaan nondimensional. Selanjutnya persamaan nondimensional diubah menjadi persamaan similaritas. Kemudian diselesaikan menggunakan metode Keller Box. Simulasi dilakukan pada partikel nano Li2O dan Fe2O3 dengan fluida dasar air. Hasil menunjukkan bahwa pada saat kecepatan aliran semakin besar maka parameter magnetik dan porositas semakin besar sedangkan volume fraction dan bilangan Prandtl semakin kecil. Pada saat temperatur semakin besar, maka parameter magnetik, porositas, dan bilangan Prandtl semakin kecil, sedangkan volume fraction semakin besar.

This research discussed analyzing the profile of velocity and temperature around the lower stagnation point of magnetohydrodynamics nano fluids flow through porous cylinder. Governing equations are derived from mass or continuity equation, momentum equation, and energy equation. Further, the dimensional governing equations are converted to the non-dimensional governing equations. Then the non-dimensional governing equations are transformed to similarity equations. Further solve the mathematical model numerically using Keller Box method. For running numerical simulation, we apply two nano fluids, i.e. nano particle Li2O dan Fe2O3 with water as basic fluid. The results show that velocity of the nano-fluid increases when parameters of magnetic and porous increase. However, the velocity of the nano fluid increases when the volume fraction and Prandtl number decrease. Further, the temperature of nano fluid increases when the parameter of magnetic, porous, and Prandtl number decrease. However, the temperature of nano fluid increases when the volume fraction increases.
