  1. 41. Numerical study of a jet impacting a heated object

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Moutaz Hammoud; [2023]
    Keywords : Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

    Abstract : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. READ MORE

  3. 42. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

    University essay from KTH/Materialvetenskap

    Author : Felix Göttfert; [2023]
    Keywords : Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Heat Transfer; Thermal Conductivity; Thermophysical Properties; Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Värmeöverföring; Termisk konduktivitet; Termofysiska egenskaper;

    Abstract : Steel has played an indispensable role in shaping our contemporary world  and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. READ MORE

  4. 43. Convolution- compacted vision transformers for prediction of local wall heat flux at multiple Prandtl numbers in turbulent channel flow

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Yuning Wang; [2023]
    Keywords : Turbulent flow; Heat transfer; Vision transformer; Convolutional neural network; Machine learning;

    Abstract : Predicting wall heat flux accurately in wall-bounded turbulent flows is critical fora variety of engineering applications, including thermal management systems andenergy-efficient designs. Traditional methods, which rely on expensive numericalsimulations, are hampered by increasing complexity and extremly high computationcost. READ MORE

  5. 44. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Wickramasooriyage Devmini Kularatne; [2022]
    Keywords : Oriented strand board; thermal decomposition; mechanical degradation; heat transfer modelling; Technology and Engineering;

    Abstract : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. READ MORE
