Expert to Present Materials Heat Transfer Findings at AMPP

Mon, 21 February, 2022

TWI principal project leader, Imran Bhamji is due to present at AMPP’s annual conference and expo in San Antonio, Texas on 8 March 2022.

Imran’s presentation, ‘Advanced Materials for Condensing Heat Transfer’ will take place as part of the ‘Geothermal Scaling and Corrosion’ session, with the presentation starting at 8:35am.

The work that informs this presentation was conducted as part of the GeoHex Project by Imran, alongside TWI colleagues Shiladitya Paul, Alan Taylor, Anna Wojdyla-Cieslak, and Garima Mittal from Leicester University and the Materials Innovation Centre (MATIC).

The process of wetting solids with liquids is important for the efficiency of heat exchangers, particularly with condensation heat transfer.

Using superhygrophobic materials, surfaces or coatings to promote dropwise condensation, rather than film-forming, is expected to give rise to next generation, high efficiency designs.

The project designed and fabricated nanoscale metal oxides using a materials-by-design approach to enhance the properties of conventional hygrophobic coatings. The novel superhygrophobic coatings that came from this consisted of a polysiloxane matrix, which provides an inherently water repellent film, and functionalised silica nanoparticles, providing bottom-up roughness.

These coatings were applied to aluminum, copper, carbon steel and stainless steel substrates, offering solutions for a range of applications.
