A Heat Transfer Modeling Study of Rail Thermite Welding
… It was found that a wider weld gap, a longer preheating time, and a higher liquid temperature help to reduce the occurrence of the most severe weld defects in thermite welds. The influence of welding conditions were summarized in defect formation maps which can be used to guide the selection …

Transient model of preheating a submerged entry nozzle
Adequate preheating of the submerged entry nozzle (SEN) is important to avoid problems such as thermal cracks and skulling, and depends on torch configuration, fuel, SEN geometry and other factors. A steady-state axisymmetric computational model of the flame, combustion reactions, and air …

Effect of silicon carbide (SiC) on mechanical and physical properties of solid state recycled aluminium aa6061 by using hot extrusion method
… temperature (T) of 450°C and 550°C, with two preheating time (t) of 1 hour and 3 hour reinforced with two volume fraction of silicon carbide (SiC) of 5 wt.% and 15 wt.%. Response Surface Methodology (RSM) utilized the factor towards the response which is Ultimate Tensile Strength (UTS), …

Ein Beitrag zur Optimierung der Betriebsweise heizungs- und raumlufttechnischer Anlagen
Im Rahmen der vorliegenden Arbeit wird gezeigt, wie ein Gebäude- und Anlagensimulationsprogramm mit bekannten Optimierungsalgorithmen gekoppelt und zur theoretischen Lösung optimaler Steuer- und Regelprobleme in der Gebäudetechnik eingesetzt werden kann. Theoretische Optimallösungen erlauben im …
