1. 11. Temperature Based Estimation of the Time-Resolved Massflux of ICE Exhaust Gas Flow

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

   Author : Mayur Khedekar; [2021]
   Keywords : ICE exhaust flow condition; Thermocouples; Resistance wire thermometers; Nu correlations; ICE exhaust Mass-fluxstudy; Heat transfer coefficient; Heat balance equation for thermocouple; Constant current anemometry; ICE-avgasflödesförhållande; Termoelement; Motståndstrådstermometrar; Nu-korrelationer; ICE-avgas Massflödesstudie; Värmeöverföringskoefficient; Värmebalansekvation för termoelement; Konstant strömanemometri;

   Abstract : The aim ofthe study was to provideinformation and experience gained with fine wire thermocouples (TCs)or resistance wire thermometers (RWTs) temperature signals to estimate the timeresolved heat transfercoefficient. Constant current method was assumed in the study and medium used in this study was air. READ MORE

3. 12. Cooling Strategy Influence on Temperature in ETD Center

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Oskar Edinger; [2021]
   Keywords : Machining; Drilling; Exchangeable tip drill; 316L Stainless steel; Thermocouple; IR Thermography; Skärande bearbetning; Borrning; Löstoppsborr; 316L Rostfritt stål; Termoelement; IR Termografi;

   Abstract : Striving for increased productivity while maintaining hole quality and high process robustness when drilling requires knowledge about the working principles of heat generation, mechanics and a proper cutting fluid that aids in cooling, lubricating and evacuating chips from the cutting zone. If the heat generated in the tool-workpiece and tool-chip interfaces does not exit the cutting zone adequately through the chips, the workpiece material or the redistribution of coolant the hole quality can be impacted negatively and breakdowns may occur which reduces overall productivity.

4. 13. Coulomb drag in parallel nanowires

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : David Dai; [2020]
   Keywords : Coulomb drag; nanowire; Physics and Astronomy;

   Abstract : In this project the transport phenomenon Coulomb drag is studied in a 1D system comprised of two nanowires in parallel. Specifically, a driving current across the active wire generated a drag current in the passive wire, and we studied how Coulomb drag influenced both the driving and drag currents. READ MORE

5. 14. Effect of conformal cooling in Additive Manufactured inserts on properties of high pressure die cast aluminum component

   University essay from Jönköping University

   Author : Ruslan Sevastopolev; [2020]
   Keywords : High Pressure Die Casting HPDC ; Additive Manufacturing AM ; Aluminum Al ; Tensile test; Cooling channels; Conformal cooling; Laser Based Power Bed Fusion of Metals PBF-LB M ; Microstructure; Secondary Dendrite Arm Spacing SDAS .;

   Abstract : Additive manufacturing can bring several advantages in tooling applications especially hot working tooling as high pressure die casting. Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. READ MORE

6. 15. Design of a Carbon Fiber Thermocouple for Elevated Temperature Measurements

   University essay from KTH/Materialvetenskap

   Author : Marcus Holmström; [2020]
   Keywords : Thermocouple; Carbon Fiber; Thermoelectrical; Electromotive Force; Polyacrylonitrile; Rayon; Termoelement; Kolfiber; Termoelektrisk; Elektromotorisk spänning; Polyacrylonitrile; Viskos;

   Abstract : Thermocouples are one of the most commonly used instruments for thermometry at elevated  temperatures. As of today, there are only a few types of thermocouples that are built to withstand a temperature beyond 1600 °C,however they usually have a temperature measurement uncertainty of around 1% at these high temperatures.
