Our latest journal paper fatigue and post-fatigue static crack characterisation of a wrinkled thick glass fibre laminate in a composite wind turbine blade This paper establishes the connection between fatigue damage in large composite structures and the characteristics of fractures on a smaller scale. https://lnkd.in/e8nfycBY Great joint work with my colleagues Ximi, Chen Chi Jen, Søren Fæster, Sina Samareh-Mousavi.

While you’re at the MEPEC (Middle East Process Engineering Conference and Exhibition) conference, be sure to stop by the e-poster session on May 7 to learn about #LummusTechnology’s SRT-h™ hybrid cracking heater, with Lummus expert, Hani Alkhalifa, on hand to answer questions and share how our short residence time heaters can improve reliability, run-length, yield and energy efficiency. #MEPEC2024

John Williams, our VP of Technical Services, was featured on a panel of experts in E-Mobility Engineering's article on thermal runaway 🔋 🔥. Here's a sneak preview of his discussion on PyroThin thermal barriers:   “Cell-to-cell barriers do not operate in isolation, so our materials are designed with a system-level approach. Our team takes into consideration how cells expand over time as they age and compress the barriers between them. By a pack’s end-of-life (EOL), the aerogel is compressed to a fraction of its original thickness. The material has a thermal conductivity lower than still air, so when it is under strain the thermal conductivity actually improves 📈”   Check out the full article here à https://lnkd.in/gmr9iZWD

"Main Cable Inspection and Strength Evaluation of Helicoidal Strand  Main Cables Using a Modified NCHRP Evaluation Approach" -Jorge Perez Armino, P.E., P.Eng. & Ahsan Chowdhury, P.Eng. - IABSE Symposium Istanbul 2023 ABSTRACT  The A. Murray MacKay Bridge (MacKay Bridge) opened to traffic in 1970 and carries four lanes of traffic over the Halifax Harbour between Dartmouth and downtown Halifax, Nova Scotia, Canada. The Bridge's main cable has been opened for detailed visual inspections several times beginning in 2002. The Owner, Halifax Harbour Bridges, retained COWI North America to perform a strength evaluation in accordance with the National Cooperative Highway Research Program (NCHRP) Report 534- Guidelines for Inspection and Strength Evaluation of Suspension Bridge Parallel Wire Cables. As the MacKay Bridge main cable is composed of 61 parallel strands with helicoidal wires, the NCHRP 534 approach (intended for parallel wires) was modified to perform the strength evaluation for cables with helicoidal wires. Based on the analysis performed, it was determined that the main cable of the MacKay Bridge has adequate capacity at this time. Additional measures to protect the cable, mainly through dehumidification, could be considered to prevent further deterioration of the main cable and extend the service life of the cable and therefore the bridge. https://lnkd.in/gVaBRbew

If you have an interest in applications of the organic Rankine cycle, this paper may be of interest to you. Our recently published paper, titled "Impact of Turbine Characteristics on Low Temperature Organic Rankine Cycles Operating with Zeotropic and Azeotropic Mixtures," delves into the influence of fluid mixtures on turbine design and performance, as well as overall cycle performance. While fluid mixtures have proven effective for heat transfer in the boiler and condenser, the same cannot be said for turbine performance. Unlike the common practice of assuming constant turbine efficiency, certain fluid mixtures and compositions have been found to adversely affect turbine performance, consequently impacting cycle net work and thermal efficiency. The paper has been published in Case Studies in Thermal Engineering: Impact factor: 6.8, Q1(92.9%) Please feel free to download the study for further insights. https://lnkd.in/ddmAmxvk
