•Darcy-Forchheimer Hybrid nanofluid flow over infinite porous disk have studied with a comparison of nanofluid.•Interfacial nanolayer of the nanoparticle discussed in the problem which shows a significant impact.•Thermal Marangoni convection have introduced to understand surface tension variation due to temperature in the system.•Entropy generation of the system studied and discussed.•These outcomes may help to understand different industrial phenomena on atomic reactor, semiconductor processing etc. Nanofluids have been used in industries due to their high heat transfer rate. The prominence is on hybrid nanomaterials as they improve more thermal conductivity of the fluids and liquid alloys. In this problem, a thermal Marangoni convection flow of nanomaterials MWCNT and MoS2 embedded in base fluid water on steady Darcy-Forchheimer flow with the conjugate effect of interfacial nanolayers have investigated. The impact of heat generation with viscous dissipation becomes extremely dominant to the flow. An appropriate resemblance conversion is being used to streamline the highly coupled and nonlinear governing equations. The similarity equations are explained by considering the shooting technique and used with the software package bvp4c MATLAB. The impact of interfacial nanolayer demonstrated through graphs on velocity and temperature for various leading parameters. Also, the result of skin friction and heat transfer are presented in tabular form. A brief analysis of various parameters is displayed through several graphs with the influence of nanofluid and hybrid nanofluid. Further, we incorporated the entropy generation as well as the bejan number. After simulation, it is specified that the Marangoni number disrupts the heat transfer rate, meanwhile, it improves with heat generation. Entropy generation is nonlinearly raised with enhancement in the permeability parameter and Brinkman number, on the other hand, it experiments that, a reverse process arises for the Bejan number with an impact of nanolayer.
