The project will study a novel idea using heat pipe technology to eliminate the need of fluid in drilling. The effect of heat pipe cooling will be investigated analytically and experimentally. During drilling, the heat pipe rotates and is subjected to centrifugal and Coriolis forces. In a conventional heat pipe, capillary force pumps fluid from the condenser to the evaporator. However, this function will be performed by centrifugal force in the proposed approach. A three-dimensional numerical analysis will be performed to predict the temperature in the drill and in the heat pipe. A companion experimental study will be performed using twist drills with heat pipes to assess the effectiveness of heat pipes in reducing tool wear and cutting fluid. Temperatures will be measured using infrared sensors and thermocouples. The research will be conducted by a multi-disciplinary team with participants from University of Wisconsin-Milwaukee, Oakland University, and Lamb Technicon. This project has the potential of simultaneously improving quality and reducing costs for drilling, by increasing drill tool life and eliminating cutting fluid. Environmental concerns provide an additional impetus towards eliminating the cutting fluid.

该项目将研究一种新的想法，使用热管技术，以消除钻井中对流体的需要。 热管冷却的效果将进行分析和实验研究。 在钻孔期间，热管旋转并受到离心力和科里奥利力。 在传统的热管中，毛细力将流体从冷凝器泵送到蒸发器。 然而，在所提出的方法中，该功能将通过离心力来执行。 将进行三维数值分析，以预测钻和热管中的温度。 将使用具有热管的麻花钻进行配套实验研究，以评估热管在减少刀具磨损和切削液方面的有效性。 将使用红外传感器和热电偶测量温度。这项研究将由一个多学科团队进行，参与者来自威斯康星大学密尔沃基分校，奥克兰大学和兰姆技术公司。 该项目有可能通过延长钻具寿命和消除切削液，同时提高钻井质量和降低钻井成本。 环境问题为消除切削液提供了额外的动力。
