1. A Study on Particle Motion and Deposition Rate : Application in Steel Flows
Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE

2. Experimental Heat Transfer, pressure drop, and Flow Visualization of R-134a in Vertical Mini/Micro Tubes
Abstract : For the application of minichannel heat exchangers, it is necessary to have accurate design tools for predicting heat transfer and pressure drop. Until recently, this type of heat exchangers was not well studied, and in the scientific literature there were large discrepancies between results reported by different investigators. READ MORE

3. Numerical Study on Steel Flow and Inclusion Behavior during a Ladle Teeming Process
Abstract : Inclusions in molten steel have received worldwide concern due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the deoxidation process, reoxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE

4. The influence of tool steel microstructure on galling
Abstract : In sheet metal forming (SMF) of materials such as stainless steels there is a major problem with transfer and accumulation of sheet material to the metal forming tool surface. The problem is known as galling; a sort of severe adhesive wear, which results in severe scratching of produced parts. READ MORE

5. Fundamental Mathematical Modeling of Gas Injection in AOD Converters with Emphasis on the Inlet
Abstract : The overall purpose of the present work has been to developa novel mathematical model of the gas injection in the AODconverter process, based on fundamental transport equations.The model development was divided into two major steps, wherethe first step involved modeling of gas injection through acylindrical nozzle at high gas flow rates (the nozzle model).
