1. Chloride Transport in Concrete under the Frost Action – An Experimental Study
Sammanfattning : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. LÄS MER
2. Temperature and heat losses simulation in core and winding of a power transformer
Sammanfattning : Simulering av temperatur och värmeförluster i kärna och lindning för en högspänningstransformator “... Ett ljus som lyser dubbelt så starkt, varar hälften så länge …”, i analogi med ljuset så kan transformatorer köras med överlast inom vissa gränser, men med följden att livslängden blir kortare.

3. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners
Sammanfattning : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. LÄS MER
4. Quality Control of a Newsprint TMP Refining Process based on Refining Zone Temperature Measurements
Sammanfattning : The ultimate goal of this study was to examine the possibility of using temperature measurements for control purposes in a TMP refining process. The study was carried out in a commercial refiner line at Holmen Paper’s Hallsta Mill, were the primary stage refiner was equipped with temperature sensors. LÄS MER
5. On the compression properties of paper - implications for calendering
Sammanfattning : The objective of this work was to study and describe thedeformation of paper in the thickness direction in a calendernip that in some cases was heated. The temperature distributionin the thickness direction was evaluated using modelexperiments. LÄS MER
