  1. 21. Exploring Flow Cytometry for Monitoring of Microbial Water Quality During Maintenance of Drinking Water Pipes

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Måns Zamore; [2021]
    Keywords : flow cytometry; microbiology; drinking water; applied microbiology; Biology and Life Sciences;

    Abstract : Faster methods of analysing microbial drinking water quality after pipe breaks or new pipe installations would have beneficial implications. This thesis investigates the use of flow cytometry and cultivation-based techniques in connection to maintenance works, and how flow cytometry can aid in the decision-making around putting drinking water pipes in operation.

  3. 22. CFD Simulation of a Fin-Tube Evaporator under icing

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Abhay Mahesh Hervatte; [2021]
    Keywords : CFD; Refrigeration; HVAC; Evaporator; Thermodynamics; Icing;

    Abstract : The study involves development of a methodology to simulate a fin-tube evaporator under icing conditions using CFD in Ansys® Academic Fluent 2021R1. It aims to build on previous studies performed on heat pumps. It was performed by Abhay M. Hervatte in collaboration with Bosch Thermoteknik AB, Tranås, SE during the spring term of the year 2021.

  4. 23. Cavitation analysis on test rig. : An experimental and CFD study executed in collaboration with Epiroc AB

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Oskar Kuoppala; [2021]
    Keywords : CFD; Cavitation; Water Hammer;

    Abstract : This master thesis project was done in collaboration with Epiroc Group Ab. Epiroc supplies high-quality drills of various types that can be used both above and below ground. A major problem in their percussive rock drills is that that cavitation is formed. Cavitation is a phenomenon that occurs when a fluid is subject to a sudden pressure drop. READ MORE

  5. 24. Efficiency Analysis of a Wave Energy Converter Penstock

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Péter László Bondár; Felix Myrsten; [2021]
    Keywords : Efficiency Analysis; Machine Design; Optimisation; Penstock; Wave Energy Converter; Effektivitetsanalys; Maskinkonstruktion; Optimering; Tilloppstub; Vågkraftverk;

    Abstract : Novige develops a wave energy converter (WEC) concept that utilizes wind-generated wave to create electricity. The system uses a float and a hydraulic cylinder to pump water up to a turbine, similar to an inverted hydro power plant. READ MORE

  6. 25. Investigation Of The Influence Of Geometrical Parameters On Heat Transfer In Matrix Cooling : A Computational Fluid Dynamics Approach

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Fabian Maletzke; [2021]
    Keywords : turbine; blade cooling; matrix cooling; latticework cooling; CFD; heat transfer; RANS;

    Abstract : Modern gas turbine blades and vanes are operated at temperatures above their material’s melting point. Active external and internal cooling are therefore necessary to reach acceptable lifetimes. One possible internal cooling method is called matrix cooling, where a matrix of intersecting cooling air channels is integrated into a blade or vane. READ MORE
