: Flow-through permeable media have a wide range of applications in biomedical engineering, geophysical fluid dynamics, and recovery and refinement of underground reservoirs and large-scale chemical applications such as filters, catalysts, and adsorbents. Therefore, this study on a nanoliquid in a permeable channel is conducted under physical constraints. : The key purpose of this research is to introduce a new biohybrid nanofluid model (BHNFM) with (Ag-G) with additional significant physical effects of quadratic radiation, resistive heating, and magnetic field. The flow configuration is set between the expanding/contracting channels, which has broad applications, especially in biomedical engineering. The modified BHNFM was achieved after the implementation of the bitransformative scheme, and then to obtain physical results of the model, the variational iteration method was applied. : Based on a thorough observation of the presented results, it is determined that the biohybrid nanofluid (BHNF) is more effective than mono-nano BHNFs in controlling fluid movement. The desired fluid movement for practical purposes can be achieved by varying the wall contraction number (α = -0.5, -1.0, -1.5, -2.0) and with stronger magnetic effects ( = 1.0,9.0,17.0,25.0). Furthermore, increasing the number of pores on the surface of the wall causes the BHNF particles to move very slowly. The temperature of the BHNF is affected by the quadratic radiation (), heating source (), and temperature ratio number (θ), and this is a dependable approach to acquire a significant amount of heat. The findings of the current study can aid in a better understanding of parametric predictions in order to produce exceptional heat transfer in BHNFs and suitable parametric ranges to control fluid flow inside the working area. The model results would also be useful for individuals working in the fields of blood dynamics and biomedical engineering.
流通渗透介质在生物医学工程、地球物理流体动力学以及地下油藏的开采与提炼和大规模化学应用（如过滤器、催化剂和吸附剂）等领域有着广泛的应用。因此，本研究在物理约束条件下对渗透通道中的纳米流体进行了研究。：本研究的关键目的是引入一种新的生物混合纳米流体模型（BHNFM），其中包含（Ag-G），并具有二次辐射、电阻加热和磁场等额外的显著物理效应。流动配置设置在扩张/收缩通道之间，这具有广泛的应用，特别是在生物医学工程中。在实施双变换方案后得到了改进的BHNFM，然后应用变分迭代法来获得该模型的物理结果。：基于对所呈现结果的深入观察，确定生物混合纳米流体（BHNF）在控制流体运动方面比单一纳米BHNF更有效。通过改变壁收缩数（α = -0.5、-1.0、-1.5、-2.0）以及更强的磁效应（= 1.0、9.0、17.0、25.0），可以实现实际应用中所需的流体运动。此外，增加壁表面的孔隙数量会使BHNF颗粒移动得非常缓慢。BHNF的温度受二次辐射（）、热源（）和温度比数（θ）的影响，这是获取大量热量的可靠方法。当前研究的结果有助于更好地理解参数预测，以便在BHNF中产生卓越的热传递，并确定控制工作区域内流体流动的合适参数范围。该模型结果对于从事血液动力学和生物医学工程领域的人员也将是有用的。
