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

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

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

    Sammanfattning : 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. LÄS MER

  3. 2. CFD study of the different inlet configurations and airflows in a room with IJV

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Christos Stiapis; [2022]
    Nyckelord :Ventilation; CFD; Impinging Jet Ventilation;

    Sammanfattning : A method of providing ventilation using impinging jets (IJV) utilizes stratification while delivering air at a high velocity. As a result of this attribute and the simplicity of its terminal construction, IJV offers an advantage over the well-known Displacement Ventilation (DV) system. LÄS MER

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

    Magister-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

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

    Sammanfattning : 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. LÄS MER

  5. 4. Boiling heat transfer of multiple impinging water jets on a hot rotary cylinder

    Magister-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :Aitor Uriarte; [2021]
    Nyckelord :Quenching; unsteady heat transfer; multiple impinging jet; boiling; rotary cylinder; fast cooling.;

    Sammanfattning : Quenching technique is widely used in industrial applications as it enhances the mechanical properties of metals such as hardness and tensile strength. This technique consists of a heating process followed by fast cooling which results in different microstructures that enhance the metal behavior. LÄS MER
