1. 1. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

   University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

   Author : Fritjof Nilsson; Yanjun Peng; [2023]
   Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

   Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

3. 2. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Cyrus Ourak Pour; [2023]
   Keywords : COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

   Abstract : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

4. 3. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Hoda Mahmoodi; [2023]
   Keywords : Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

   Abstract : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. READ MORE

5. 4. Investigation and evaluation of optical distance sensors

   University essay from Uppsala universitet/Signaler och system

   Author : Olof Wigzell; [2022]
   Keywords : optics; radiometry; senssor; microcontroller; irradiance; circuit design; calibration; validation;

   Abstract : Optical sensors are among the sensors that are often used for distance measurements. An optical distance sensor is basically made of a light emitter (Tx) such as a light emitting diode (LED), a light receiver (Rx) such as a photosensitive transistor, and a circuit supporting the operation of the Tx and Rx.

6. 5. Rocket Jet Impinging on a Surface

   University essay from KTH/Teknisk mekanik

   Author : Javier Capel Jorquera; [2022]
   Keywords : Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

   Abstract : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. READ MORE
