Abstract

Prior research suggests that the use of nanotechnology may greatly improve the efficiency of enhanced oil recovery methods, especially hot fluid injection. The thermophysical characteristics of the nanofluid may have an enormous effect on how well the injection process works. However, it takes both time and resources to conduct laboratory analyses of the effects of thermophysical characteristics on the effectiveness of nanofluid-based improved oil recovery methods. Computational models can effectively forecast the thermophysical characteristics of nanofluids and how they affect oil recovery efficiency, which helps overcome this difficulty. The current study investigates the flow of vacuum residue (VR) fluid, which generates entropy when suspended graphene oxide (GO) nanoparticles. When mixed convection and variable thermal conductivity are present, a static/moving wedge allows the nanofluid to propagate. The continuity, energy, entropy, and momentum equations form the foundation of the governing model. We use certain similarity variables to simplify the suggested mathematical formulations into forms for nonlinear differential equations (DEs). We show the results of the reduced equations using the Chebyshev collocation method. We present the graphical and numerical results for all the emerging parameters. For enhanced oil recovery applications, the current results are beneficial.

氧化石墨烯/真空残渣纳米流体提高采收率的热物理性质计算研究
先前的研究表明,纳米技术的使用可以大大提高提高采收率方法的效率,特别是热流体注入。纳米流体的热物理特性可能对注入过程的效果产生巨大影响。然而,对热物理特性对基于纳米流体的提高采收率方法有效性的影响进行实验室分析需要时间和资源。计算模型可以有效地预测纳米流体的热物理特性及其对采收率的影响,有助于克服这一难题。本研究研究了悬浮氧化石墨烯纳米颗粒时产生熵的真空残渣(VR)流体的流动。当混合对流和可变热导率存在时,静态/移动的楔子允许纳米流体传播。连续性、能量、熵和动量方程构成了控制模型的基础。我们使用某些相似变量将建议的数学公式简化为非线性微分方程的形式。我们用切比雪夫配置法给出了简化方程的结果。我们给出了所有新出现的参数的图形和数值结果。对于提高采收率的应用,目前的结果是有益的。
