  1. 1. Neonatal water and heat exchange : The influence of environmental factors and infant maturity

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gunnar Sjörs; Uppsala universitet.; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Neonatal; transepidermal water loss; respiratory water loss; radiant heat; heat exchange; water loss; incubators; Pediatrik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Paediatric medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Pediatrisk medicin; pediatrik; Pediatrics;

    Abstract : The environment provided by commonly used infant incubators, the effect of radiantheat and exposure to cold air on the exchange of water and heat between newborninfants and their environment, and the water loss through the skin of infants born at24-25 weeks of gestation were investigated. The evaporation of water from the skinwas measured by the gradient method. READ MORE

  2. 2. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Abstract : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. READ MORE

  3. 3. Modeling and Performance Analysis of Alternative Heat Exchangers for Heavy Vehicles

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Wamei Lin; Lunds universitet.; Lund University.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Countercurrent flow; Graphite foam; Heat exchanger; Thermal performance; Computational fluid dynamics;

    Abstract : Popular Abstract in English Low fuel consumption, and reduced exhaust emissions, as well as improved performance and durability become much more important than before for the vehicle industry. These requirements lead to a number of additional equipment installed in the vehicles. READ MORE

  4. 4. Computational Analysis of Heat Transfer and Fluid Flow with Relevance for IC-Engine Cooling

    University dissertation from KFS AB

    Author : Sassan Etemad; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; turbulence models; Heat transfer; curved duct; secondary flow; IC-engine cooling; Gases; Thermal engineering; applied thermodynamics; Teknik; Technological sciences; plasma; Gaser; fluiddynamik; plasmas; fluid dynamics;

    Abstract : Modern IC-engines produce more power per displaced volume and operate at higher combustion pressures and temperatures. In addition, engine structure materials such as aluminium and magnesium alloys, which are more sensitive to thermal loads, are more commonly used. READ MORE

  5. 5. Heat loss to the ground from a building : slab on the ground and cellar

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Carl-Eric Hagentoft; [1988]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat loss; heat transfer in the ground; thermal analysis; slab; cellar; crawl-space;

    Abstract : Heated buildings induce a heat flow from the building foundation into the ground. The topic of this thesis is the thermal process in the ground and, in particular, the heat losses from the building to the ground. Foundations of the three types slab on the ground, cellar, and crawl-space are dealt with. The crawl-space is treated in separate report. READ MORE
