This paper is designed to analyze the entropy production in hybrid nanofluid $\left(\text{MnZnF}{\mathrm{e}}_2{\mathrm{O}}_4\text{–NiZnF}{\mathrm{e}}_2{\mathrm{O}}_4\text{–}{\mathrm{H}}_2\mathrm{O}\right)$. Marangoni convection is the phenomena of mass transfer between two phases of fluids when gradient of surface tension take place. Darcy–Forchheimer flow is incorporated in momentum equation. In thermal equation we are studying additional effects of nonlinear heat source sink with thermal radiation. Heterogeneous–homogeneous reactions are also studied. Transformations are used to convert our system of equations in to ODE’s so we can easily solve them by using ND Solve MATHEMATICA. Characteristics of fluid (temperature, entropy generation, velocity, Bejan number, Nusselt number, concentration and skin friction) are calculated and studied in detail. Results are presented through graphs. Flow resists due to enhancement in Marangoni ratio parameter. Temperature boosts up for higher thermal and exponential heat source sink. Concentration field is rising for greater heterogeneous parameter. Entropy and Bejan have contrast behavior for Brinkman number.

本文旨在分析混合纳米流体中的熵产生 $\left(\text{锰锌}{\mathrm{电子}}_2{\mathrm{哦}}_4\text{–NiZnF}{\mathrm{电子}}_2{\mathrm{哦}}_4\text{——}{\mathrm{H}}_2\mathrm{哦}\right)$. Marangoni 对流是当发生表面张力梯度时两相流体之间的传质现象。Darcy-Forchheimer 流包含在动量方程中。在热方程中，我们正在研究具有热辐射的非线性热源汇的附加效应。还研究了非均相反应。转换用于将我们的方程组转换为 ODE，因此我们可以使用 ND Solve MATHEMATICA 轻松求解它们。详细计算和研究了流体的特性（温度、熵产生、速度、Bejan 数、Nusselt 数、浓度和皮肤摩擦）。结果通过图表呈现。由于 Marangoni 比率参数的增强而导致流动阻力。温度升高以获得更高的热源和指数热源。对于更大的异质参数，浓度场正在上升。Entropy 和 Bejan 对 Brinkman 数有对比行为。
