  1. 21. Inverse Heat Conduction problem of the Quenching a Rotary Cylinder by Multiple Water Impinging Jets

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : Leticia Uriarte Sabín; [2021]
    Keywords : Quenching; Inverse solution; Unsteady heat conduction; Generalized minimum residual method; rotary cylinder;

    Abstract : The thesis deals with solving the time dependent inverse heat conduction and heat transfer problem of the quenching process of a rotary solid cylinder by multiple impinging water jets. The development of such investigation consists of two parts that complement each other. READ MORE

  2. 22. Deep learning for non-intrusive sensing in turbulence with passive scalars

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Arivazhagan Geetha Balasubramanian; [2021]
    Keywords : Turbulent boundary layer; passive scalar; direct numerical simulation; Prandtl number; Machine learning; convolutional neural network; Turbulent gränsskikt; passiv skalär; direkt numerisk simulering; Prandtl-nummer; maskininlärning; faltningsneurala nätverk;

    Abstract : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. READ MORE

  3. 23. Verification of the local similarity theory above forests

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Yasmin Hubmann; [2021]
    Keywords : Forest Meteorology; Boundary Layer Meteorology; Wind Energy; Local Similarity Theory; Monin–Obukhov Similarity Theory; Flux-Gradient Formulation; Richardson Number Formulation; Turbulence Statistic; Rotor Equivalent Wind Speed; Grenzschicht-Meteorologie; Forstmeteorologie; Windenergie; Lokale Ähnlichkeitstheorie; Monin–Obukhov’sche Ähnlichkeitstheorie; Fluss-Gradient-Ähnlichkeit; Gradient-Richardson-Zahl Beziehung; Turbulenzcharakteristiken; Rotor-äquivalente Windgeschwindigkeit; Skogsmeteorologi; Gränsskiktsmeteorologi; Vindenergi; Lokal Similaritetsteori; Monin–Obukhov Similaritetsteori; Flöd-Gradient Relation; Richardson Gradienttal Relation;

    Abstract : In this study, the local similarity theory functions were calculated with two different approaches and on the other hand the mean hub height wind speed was compared with the rotor equivalent wind speed. Both calculations are based on two independent data-sets from measurement campaigns Hornamossen and Ryningsnäs which were conducted in the south of Sweden between May 2015 and June 2017, and November 2010 and February 2012.

  4. 24. Damage Criteria for Fibre Optic Cables Exposed to Fire - Using data transfer as functional criterium

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Joakim Åström; Sofia Lindahl; [2021]
    Keywords : Cable; fibre optic cables; data transfer; data loss; functional criterium; damage criteria; bend diameter; temperature; fire conditions; heat flux; cone calorimeter; probabilistic distribution; risk analysis; Technology and Engineering;

    Abstract : The aim of this master thesis was to analyse the possibility to use fibre optic cables for critical safety features in high reliability facilities. In more detail, this report investigates how transferred data in fibre optic cables are affected by fire and if there is any risk that the data becomes corrupted or lost when exposed to fire conditions.

  5. 25. Modeling and optimisation of a rotary kiln reactor for the processing of battery materials

    University essay from KTH/Kemiteknik

    Author : Danial Khawaja; [2021]
    Keywords : Granular flow; rolling mode; suspension model; two-fluid model; multiphase flow; Granulärt flöde; rullningsläge; suspensions modell; tvåvätskemodell; flerfasmodell;

    Abstract : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. READ MORE
