  1. 1. CFD investigation of a unit cell inside a Plate Heat Exchanger

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Mattias Ly; [2023]
    Keywords : Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Abstract : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. READ MORE

  3. 2. Managing a Work Environment using Sensor Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mattias Lind; Fredrik Karlsson; [2021]
    Keywords : Embedded Systems; Work Environments; Sensor Networks; Inbyggda System; Arbetsmiljöer; Sensornätverk;

    Abstract : During the last decade sensor networks and Internet of Things have been gaining a lot of attention. One area where it is still fairly unused is to manage work environments. With sensor networks and Internet of Things devices it is possible to measure and control noise levels, air quality and most other aspects of reality. READ MORE

  4. 3. Evaluation of Traction Control Systems for an Electric Forklift Truck

    University essay from Linköpings universitet/Fordonssystem

    Author : Mattias Karlsson; Sebastian Johansson; [2021]
    Keywords : forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

    Abstract : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.

  5. 4. Hur påverkas skogslevande myror av den introducerade contortatallen?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Mattias Andreasson; David Karlsson; [2020]
    Keywords : Pinus sylvestris; Pinus contorta; tall; Formicidae; myror; biodiversitet; boreal; skog;

    Abstract : I Sverige finns det intresse för nyintroducerade trädarter inom skogsbruket s.k. exoter. Exoterna kan påverka skogens biodiversitet negativt. READ MORE

  6. 5. Wire and Arc Additive Manufacturing : Pre printing strategy for torque arm

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mattias Karlsson; Axel Magnusson; [2020]
    Keywords : wire; and; arc; additive; manufacturing; 3d printing; waam; wire and arc additive manufacturing; welding; toruqe arm; AM;

    Abstract : Wire and Arc Additive Manufacturing (WAAM) is a novel Additive manufacturing method. It is a high deposition rate process which can be suitable for producing low to medium quantities of medium to large sized components. Because it is such a novel method, there are still somechallenges to solve for the method to be useful. READ MORE
