  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. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model

    University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära

    Author : Micaela Hamberg; Signe Dahlin; [2019]
    Keywords : VOF; RANS; Navier-Stokes; Spillway; Discharge tunnel; ANSYS; Fluent; CFD; Grid convergence index; Design of spillway; Cavitation; Gambit; k-epsilon; Ansys Gambit;

    Abstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE

  3. 3. Evaluation of New Features for Extractive Summarization of Meeting Transcripts : Improvement of meeting summarization based on functional segmentation, introducing topic model, named entities and domain specific frequency measure

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

    Author : Emilio Marinone; [2019]
    Keywords : ;

    Abstract : Automatic summarization of meeting transcripts has been widely stud­ied in last two decades, achieving continuous improvements in terms of the standard summarization metric (ROUGE). A user study has shown that people noticeably prefer abstractive summarization rather than the extractive approach. READ MORE

    Abstract : It is reported that cooking can generate many kinds of airborne pollutants,which pose serious threats to human health. Kitchen range-hood is themost effective and popular equipment to exhaust the airborne pollutants,including smoke and oil particle in people’s daily life. READ MORE

  5. 5. Numerical Modeling of Aluminum Sampling Process

    University essay from KTH/Materialvetenskap

    Author : Ming Yang; [2019]
    Keywords : Numerical modeling; Aluminum sampling; Solidification process; Inclusion distribution; Ansys Fluent.;

    Abstract : Castings of aluminum alloys are widely used in the automotive and aerospace industries since they play a significant role in improving the performance and fuel efficiency. In aluminum industries, sampling is the most common method to evaluate the inclusion levels which is a key indicator for the quality of the aluminum alloys. READ MORE
