The main intention of this article is to explore the significance of electronmagnetohydrodynamic (EMHD) dusty nanofluid on the stagnation point flow in the presence of radiation and Ohmic heating. Water is considered as base fluid with single-wall carbon nanotubes along with suspended dust particles. The numerical solutions for both dusty phase and fluid phase differential systems are obtained by using Runge Kutta 4th order with shooting method. Influence of embedded parameters such as Biot number, electric field, viscous dissipation, magnetic field, thermal radiation, Joule heating and stagnation point flow are presented graphically. Dust particles play a significant role in food pharmaceutical industries particularly for efficient cultivation of microorganisms and also these type of studies may be applicable in atmospheric fields, wastewater treatment, metal objects covered with plastic materials and solids drying. The higher values of electric field parameter (E) increases the fluid phase velocity and dusty phase velocity. An increase in the thermal radiation parameter releases thermal energy into the flow, so this energy helps to increase the fluid phase temperature and dusty phase temperature. The fluid phase temperature and dusty phase temperature declines with increasing the electric field parameter for dusty fluid and dusty nanofluid cases.

本文的主要目的是探讨在存在辐射和欧姆加热的情况下电磁流体动力学（EMHD）尘土纳米流体对停滞点流动的重要性。水被认为是具有单壁碳纳米管以及悬浮灰尘颗粒的基础流体。尘埃相和液相微分系统的数值解都是通过使用Runge Kutta四阶射击方法获得的。图形化地显示了诸如Biot数，电场，粘性耗散，磁场，热辐射，焦耳热和停滞点流等嵌入式参数的影响。灰尘颗粒在食品制药行业中扮演着重要角色，尤其是对于微生物的高效培养而言，这些类型的研究也可能适用于大气领域，废水处理，用塑料材料覆盖的金属物体和固体干燥。较高的电场参数值（E）增加了流体相速度和粉尘相速度。热辐射参数的增加将热能释放到流中，因此该能量有助于提高液相温度和粉尘相温度。对于多尘流体和多尘纳米流体情况，随着电场参数的增加，流体相温度和尘埃相温度下降。
