In the present work, thermoelectric power generation from cavities with ventilation ports is considered by using a rotating conic object and carbon-nanotube particles in the base fluid. Effects of different pertinent parameters such as Reynolds numbers of hot and cold fluid streams (between 200 and 1000), rotational Reynolds number of the conic object (between −400 and 400), size (between 0.05H and 0.25H) and horizontal location (between 0.2H and 0.6H) of the object and nanoparticle volume fractions of nanoparticles (between 0 and 0.02) on fluid flow, interface temperature and generated thermoelectric output power characteristics were studied. It was observed that exit port location of the hot cavity, fluid stream Reynolds number and rotational Reynolds number of the object have significant impacts on the fluid flow, interface temperatures and output power. When lowest and highest fluid stream Reynolds number is compared, 43.75% variations in the output power is obtained. The clockwise rotation of the conic object results in higher thermoelectric power generations as compared to a stationary cone while up to 49.20% increments of the power is attained at the highest rotational speed. The size of the rotating object is influential on the power generation while its horizontal location has slight effects. When nanofluid at the highest solid volume fraction configuration is compared with pure water case, 20% increment in the thermoelectric power is obtained. A predictive model for power estimations with adaptive network-based fuzzy inference system is proposed for input parameters of hot and cold fluid stream Reynolds number and rotational Reynolds number of the conic object which delivers accurate and fast prediction results.

在目前的工作中，考虑通过使用旋转的锥形物体和基础流体中的碳纳米管颗粒来从具有通风口的腔中产生热电。不同相关参数的影响，例如冷热流体流的雷诺数（200至1000），圆锥体的旋转雷诺数（-400至400），尺寸（0.05H和0.25H之间）和水平位置（研究了在0.2H至0.6H之间的目标，以及纳米粒子在0、0.02之间的流体体积，界面温度和产生的热电输出功率特性。观察到热腔的出口位置，物体的流体流雷诺数和旋转雷诺数对流体流动有显着影响，接口温度和输出功率。比较最低和最高流体流雷诺数时，可获得43.75％的输出功率变化。与固定圆锥体相比，圆锥体的顺时针旋转会产生更高的热电发电量，而在最高旋转速度下，功率增量可达到49.20％。旋转物体的大小对发电有影响，而旋转物体的水平位置则影响不大。当将具有最高固体体积分数构型的纳米流体与纯水的情况进行比较时，可获得20％的热电功率增量。
