Abstract

Penelitian mengenai manufaktur dan energi semakin berkembang. Salah satu studi yang tekait dengan penelitian ini adalah fluida. Pada penelitian ini digunakan pemodelan matematika untuk menyelesaikan permasalahan tersebut. Penelitian ini mengkaji mengenai aliran fluida magnetohidrodinamik tak tunak dengan konveksi paksa pada fluida micropolar yang melewati bola berpori bermagnet. Persamaan pembangun yang digunakan pada penelitian ini didapat dari persamaan kontinuitas, persamaan momentum, persamaan momentum angular, dan persamaan energi. Persamaan pembangun dimensional ditransformasikan kedalam persamaan non dimensional kemudian dirubah kedalam persamaan similaritas dan diselesaikan secara numerik dengan menggunakan skema Keller-Box. Hasil simulasi menunjukkan kurva kecepatan menurun ketika parameter magnetik, porositas, dan micropolar meningkat. Kurva mikro rotasi dan temperatur meningkat seiring meningkatnya parameter magnetik, parameter porositas, dan parameter micropolar. Tetapi kurva temperatur menurun ketika bilangan prandtl meningkat. ================================================================ The research of manufacturing and energy is growing. One of the studies about this research is fluids. This research uses mathematical modeling to solve the problem. This research considers unsteady magnetohydrodynamics with forced convection of micropolar fluid through a magnetic porous sphere. Governing equations that used derivated by continuity, momentum, angular momentum, and energy equations. Dimensional equations are transformed to non dimensional equations and then, it will be converted to similarity equations. The similarity equations are solved numerically using Keller-Box scheme. It could be concluded that the velocity curve decreases when magnetic, porosity, and micropolar parameters increase. Microrotation and temperature curve increase when the magnetic, porosity, and micropolar parameters increase. But temperature declines with the increasing of Prandtl number.
