1. 21. Modelling and Validation of Evaporation Systems; Mass & Energy Balances

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Maja Sondell; [2023]
   Keywords : Evaporation; Evaporation Systems; Modeling; Python; Chemical Engineering; Kemiteknik; Evaporation Rate; Overall Heat Transfer Coefficient; Technology and Engineering;

   Abstract : To evaluate the performance of evaporation systems, performance parameters such as overall heat transfer coefficient and evaporation rate need to be evaluated. These parameters are difficult measure and therefore need to be calculated using other measured data. READ MORE

3. 22. Numerical Modelling of Combined Forming and Punching of Sheet Metal for Heat Exchanger Applications

   University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Author : Erik Stålbrand; [2023]
   Keywords : Solid Mechanics; Material Modelling; Damage Modelling; Sheet Metal Damage; Punching Simulation; Forming Simulation; Heat Exchanger; Technology and Engineering;

   Abstract : In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a design process.

4. 23. Full Material Declaration - A case study on the readiness for declaring Full Material Declaration of chemical substances in components, used in finished products

   University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Author : William Lövdahl; [2022]
   Keywords : full material disclosure; full material declaration; FMD; chemical substances in products; CiP; information flow in supply chain; chemical declaration; information flow; chemical; mapping chemical substances; tracking chemical substances; transparency in the supply chain; supplier data sharing; readiness and chemical management; chemical management; chemical disclosure; Earth and Environmental Sciences;

   Abstract : The production and use of chemicals has grown exponentially over the past 50 years. Although the knowledge of hazards and risks associated with chemicals towards humans and the environment has increased, we know frightenedly little about how dangerous these might become when part of finished products.

5. 24. Frost prediction in heat exchangers : The influence of relative humidity and outdoor temperature on frost formation in plate heat exchangers

   University essay from KTH/Betongbyggnad

   Author : Emin Osmic; [2022]
   Keywords : ;

   Abstract : Frost in Mechanical Ventilation with Heat Recovery (MVHR) often occurs when indoor air is humid and outdoor air is cold. Warm and humid air from the rooms condensates or sublimates when it becomes cold enough, causing frost to grow in the heat exchanger channels. READ MORE

6. 25. Purification of Volatile Organic Compounds in Channeled Ventilation Pipes at the Sysav Water Treatment Plant for Hazardous Waste

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Erik Wiktorsson; [2022]
   Keywords : VOC; Zeolite; Catalytic combustion; Sysav; Chemical Engineering; Chemistry; Technology and Engineering;

   Abstract : Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to be the method of greatest feasibility and is the subject of further investigation.
