  • Numerical simulation for treatment of hypothermia based on vascular interventional Direct Heating System.
    Journal of Thermal Biology, 2018
    Co-Authors: Yuanyuan Qiao, Dajin Zhang, Zhi-zhu He
    Abstract:

    Abstract The treatment of hypothermia suffered by naval fighters owing to seawater immersion has been a focus of research in recent years. Currently, the treatment of hypothermia in China is limited to external rewarming, which is of low efficiency and is not effective for patients suffering moderate to severe hypothermia. We thus proposed a vascular interventional Heating method which Directly heats the blood flow via a minimally invasive Heating needle for rewarming. And a numerical simulation using a compartment model based on finite difference method was conducted. A set of whole body Heating treatment simulation was also developed. Appropriate treatment parameters and procedures can be set and adjusted based on patient physical parameters. Here temperature response curves of different Heating modes were obtained and analyzed. It was demonstrated that the desired thermal response can be achieved by adjusting the Heating power and Heating time, ensuring controllable accuracy in the treatment of patients with severe hypothermia. The proposed treatment for hypothermia is a new and effective alternative, and further progress is expected in clinical trials.

  • hot incremental forming of magnesium and aluminum alloy sheets by using Direct Heating System
    Proceedings of the Institution of Mechanical Engineers Part B: Journal of Engineering Manufacture, 2013
    Co-Authors: Le Van Sy, Nguyen Thanh Nam
    Abstract:

    This article presents the use of an electrically assisted manufacturing method in the incremental sheet forming process to improve formability, surface quality, and geometric accuracy. This System utilizes a Direct current source connected Directly to a metal sheet through two electrodes at opposite edges to conduct heat based on Joule’s effect. The approach produces a homogeneous Heating zone in the whole metal sheet with very short ramping time. In this work, the Heating System is designed to serve the investigation of formability, geometric accuracy, and surface roughness of the hot incremental forming technology. Three main results expected from this System are the influence of the processing parameters on the formability, the ability to improve accuracy and formability, and the reduction or elimination of springback effects in the deformation of high-strength aluminum alloy sheets (AA5055) and magnesium alloy sheets (AZ31).
