论文摘要
在几乎所有通常不考虑并研究理想案例的问题中，不确定性在几乎所有问题中都起着重要特征。因此，后果成本更高，需要模型预测。鉴于这些，本文在可变磁场下研究了纳米流体传热问题，该磁场具有不确定的有界参数以及对系统磁场变量的不确定性的分析影响。此处报道了速度，温度和浓度曲线的变化，并在此报道了上述问题的不确定性。一个面孔的主要挑战是不确定性的存在使该系统变得复杂。因此，应该开发替代想法，以便可以克服同样的想法。因此，涉及的不确定参数被视为间隔，并且使用一个参数映射技术。有关上述问题的详细分析，一种半分析方法。同质扰动方法与转换技术相适应。在这里，吸气参数，挤压数和hartmann数字被视为间隔。然后考虑到这些参数的不同组合，解决了问题，并且对上述问题的敏感性进行了分析。最后，基于敏感性，已经建立了不确定参数与上述系统之间的关系。
Uncertainties plays an important character in almost every problem which generally not considered and ideal cases are studied. As such, the consequences cost more and need model prediction. In view of these, this paper investigates nanofluid heat transfer problem under a variable magnetic field with uncertain bounded parameters and analyzed effect of uncertainness over the field variables of the system. The variations of velocity, temperature and concentration profiles with the uncertainness for the said problem are reported here. The main challenge one face is the presence of uncertainties make the system complicated to study. So, alternate idea should be developed such that one can overcome the same. Hence, the involved uncertain parameters are considered as intervals and one parametric mapping technique is used for the same. For detail analysis of the said problem a semi analytical method viz. homotopy perturbation method is adapted with the transformation technique. Here, the suction parameter, squeeze number and Hartmann numbers are considered as intervals. Then considering different combinations of these parameters the problem is solved and sensitiveness of the same for the said problem is analysed. Finally, based on the sensitiveness, a relation of between the uncertain parameters with the mentioned system has been established.
