MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202631045177 A) filed by National Institute Of Technology, Jamshedpur, Jharkhand, on April 8, for 'a heat exchanger tube fitted with a plain twisted tape insert for heat transfer enhancement.'
Inventor(s) include Kumari, Anuradha; and Kumar, Dr. Parmanand.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "A heat exchanger tube assembly and method are disclosed for enhancing convective heat transfer in internal tube flow. The assembly includes a circular tube defining an internal flow passage and a plain twisted tape insert positioned within the flow passage to induce swirl flow and promote mixing, thereby improving heat transfer compared with a tube without the insert. In an example configuration, the tube has an internal diameter of about 20 mm and the twisted tape has a thickness of about 2 mm. The insert may be selected with a twist ratio defined as a pitch-to-width ratio, with disclosed values of 3, 4, or 5. A method of use includes fitting the tube with the insert and flowing a working fluid through the tube under turbulent-flow conditions, optionally at a Reynolds number from 10,000 to 18,000, and optionally using a copper oxide nanofluid at 2% volume concentration under constant wall-temperature condition."
