The thin needle is perspectived as an object of revolution where its thickness is lesser in comparison to boundary layer thickness. Therefore, the flow deformed by a thin moving needle has significant impact on technological and industrial applications, like, electronic devices, hot wire anemometer and geothermal power generation. Hence, this article presents a mathematical analysis of flow using stretching mechanism of thin needle. The hybrid nanomaterial is represented using the MoS2 (molybdenum disulfide) and SiO2 (silicon dioxide) nanoparticles. Physical influence of mixed convection on slip movement of hybrid nanofluid via movable needle is explored. The impact of thermal slip is encountered in the current analysis. Additionally, stratification impacts along with heat generation/absorption phenomenon are also retained in the study. The simplified governing equations are transmuted into non-dimensional equations and then are analytically solved. A homology method is utilized to find the convergent solutions. Physical explanation of velocity and heat transfer mechanism is debated in detail under pertinent parameters. Force of drag and Nusselt number are elaborated graphically. In this analysis, stratified parameter adversely affects the rate of heat transfer. Moreover, mixed convective phenomenon assisting the flow features.
