  1. 1. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

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

    Author : Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
    Keywords : ;

    Abstract : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. READ MORE

  2. 2. Modelling of a Generic Aircraft Environmental Control System in Modelica

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Sabin Poudel; [2019]
    Keywords : ECS; Environmental Control System; Modelica; Object oriented Modeling; TTECCS library; bootstrap system;

    Abstract : This thesis documents the modelling of generic Environmental Control System(ECS) of an aircraft in Modelica by utilizing components from free version of theTTECCS (Technical Thermodynamic Environmental Control and Cooling Systems) library. In doing so, components used for developing ECS from the TTECCS library are mathematically verified with theoretical formula in MATLAB. READ MORE

  3. 3. Horizontal wastewater heat recovery heat exchanger, a model

    University essay from KTH/Energiteknik

    Author : Joakim Nyholm; [2019]
    Keywords : ;

    Abstract : The residential and service sector amounts to approximately 40 percent of Sweden’s entire energy demand. In which 90 percent of that is used by households and non-residential buildings. All in all about 80 TWh are used for heating and the provision of hot water in households and non-residential buildings. READ MORE

  4. 4. Smart Maintenance using System Identification

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Usama Haider; [2019]
    Keywords : System Identification; Nonlinear Systems; Maintenance;

    Abstract : This project discusses the use of System Identification for Smart Maintenance. System Identification is the process of finding a mathematical model of a system using empirical data. The mathematical model can then be used to detect and predict the maintenance needs, which is considered as Smart Maintenance. READ MORE

  5. 5. Potential measures and improvements in energy consumptions regarding ventilations systems with heat recovery

    University essay from KTH/Byggteknik och design; KTH/Byggteknik och design

    Author : Suat Uludag; Helmut Diliwi; [2019]
    Keywords : Ventilation System; System upgrade; Heat recovery; Energy consumption; Ventilationssystem; Systemuppgradering; Värmeåtervinning; Energianvändning; Energiförbrukning;

    Abstract : The ventilation system is in itself a huge necessity in our everyday life as it provides sufficient amount of fresh air to our indoor climate, while it simultaneously circulates the residing air pollutants out of the building. Although, for this to be made possible, large amounts of energy is required to be consumed, which in turn leads to an increased energy cost. READ MORE
