The aim of this paper is to study approximate analytical unsteady flow and heat transfer analysis of CNTs nanofluid over stretching sheet for the improvement of heat assignment ratio. The present work has some important application in industry and engineering because the heat transfer ratio of nanofluid is larger compared to other fluid. With the help of defined similarity transformation, the nonlinear partial differential equations is converted to nonlinear ordinary differential equations. The model of nonlinear ordinary differential equations are then solved by Optimal Homotopy Asymptotic Method. The impact of different parameters are then interpreted using graphs in the form of velocity and temperature profiles. The influence of skin friction coefficient and Nusselt number is presented in the table form.
本文的目的是研究碳纳米管纳米流体在拉伸片上的近似解析非定常流动和换热分析,以提高换热比。由于纳米流体的传热比其他流体大,本研究在工业和工程上具有重要的应用价值。利用定义的相似变换,将非线性偏微分方程转化为非线性常微分方程。然后用最优同伦渐近法求解非线性常微分方程模型。然后用速度和温度曲线形式的图形来解释不同参数的影响。表面摩擦系数和努塞尔数的影响以表格形式给出。

Dengue remains among the major causes of mortality worldwide. Manyresearch and medical institutions are still investigating a treatment or vaccineand vector control that would be a key strategy for dengue fever prevention.We introduce Intelligent Mosquito Spray Dispenser system X’MOS-IOT, aninnovative concept that includes IR4.0 for the cloud storage automation as wellas data analytics and exchange across cyber-physical systems and cognitivecomputing. The X’MOS-IOT provides a solution for spray interval automationusing sensor and battery optimizations with direct Wifi module technology. Thedevice is equipped with X’MOS spray mini aerosol repellent, offering effectiveenvironmentally friendly Aedes mosquito control. This all-in-one systemensures a mosquito-free environment in your home. The implementation showsthe X’MOS-IOT system is able to update the level of each X’MOS in X’MOSIOTdevices, reducing the cost of manual human checking for X’Mos refill.
登革热仍然是全世界死亡的主要原因之一。许多研究和医疗机构仍在研究一种治疗方法或疫苗和病媒控制,这将是预防登革热的一项关键战略。我们推出智能蚊香喷雾器系统X 'MOS-IOT,这是一个创新概念,包括用于云存储自动化的IR4.0,以及跨网络物理系统和认知计算的数据分析和交换。X 'MOS-IOT提供了一种使用传感器和电池优化的喷雾间隔自动化解决方案,并采用直接Wifi模块技术。该设备配备了X 'MOS喷雾微型气溶胶驱蚊剂,提供有效的环境友好的伊蚊控制。这个一体化的系统确保了你家里没有蚊子的环境。实施表明,X 'MOS - iot系统能够更新X ' mosiot设备中每个X 'MOS的水平,降低人工检查X 'MOS填充的成本。
