Entropy generation (EG) is a key attribute of every heat transfer development and helps to diminish the irreversibility factor in a system. EG examination finds tremendous uses in numerous conventional industrial sectors involving fluid flows and heat transfer. Therefore, the current analysis is concerned with the impacts of EG and velocity slip on MHD peristaltic flow (PF) for an incompressible liquid in a diverging tube using a lubrication approach i.e., $\left(\epsilon <<1\right)$ and $\left(\mathrm{Re}\to 0\right)$. Closed-form outcomes for velocity, pressure gradient, pressure rise, temperature field, entropy generation, and Bejan number are acquired. The deviation of pertinent parameters on the flow quantities is outlined and deliberated. The present results agree well with the existing literature. It is established that velocity displays a declining behavior in the tube center, and it enhances almost close to the tube walls for higher magnetic parameter values. The rise in magnetic parameter diminutions the tube liquid temperature however, the reverse trend is distinguished for Brinkmann number. Further, it is found that EG diminution in the central part of the tube however it improves close to the tube walls. A validity of analytical outcomes for the velocity of the fluid is made numerically by MATLAB through bvp4c code.

熵产生（EG）是每个传热发展的关键属性，有助于减少系统中的不可逆因素。EG检查在涉及流体流动和传热的众多常规工业领域中发现了巨大的用途。因此，当前的分析关注的是EG和速度滑移对采用润滑方法的发散管中不可压缩液体的MHD蠕动流（PF）的影响，即$（\epsilon <<\mathrm{1个}）$ 和 $（\mathrm{回覆}\to 0）$。获取速度，压力梯度，压力升高，温度场，熵生成和Bejan数的闭式结果。概述并讨论了流量相关参数的偏差。目前的结果与现有文献非常吻合。可以确定的是，速度在管中心显示出下降的行为，并且对于更高的磁参数值，它几乎增强到管壁附近。磁参数的增加减小了管液温度，但是对于Brinkmann数却有相反的趋势。此外，发现在管的中央部分的EG减小，但是在靠近管壁的地方EG减小。MATLAB通过bvp4c代码以数值方式确定了流体速度的分析结果的有效性。
