Bioresources are used in different production systems as materials as well as energy carriers. The same is true for fossil fuel resources. This study explored whether preferential resource usages exist, using a building insulation system as an example, with regard to the following sustainability criteria: climate impact, land, and fossil fuel demand. We considered the complete life cycle in a l...

Abstract: properties of AA6082 aluminum alloy. Considering that aging phenomenon affects the distribution of alloying elementin matrix, and the fact that different distribution of alloying elements has different impediments to dislocationmovement, a material model based on microstructure, has been developed in this research. A relative volume fractionor mean radius of precipitations is introduc...

in this study, the effects of linear and rotational speed of the friction stir welding tool was investigated on the heat generation and distribution at surface and inside of workpiece, material flow and geometry of the welding area of poly methyl methacrylate (pmma) workpiece. the commercial cfd fluent 6.4 software was used to simulation of the process with computational fluid dynamic technique...

This article examines options of an innovative design of intralogistic systems by interfacing small-scaled modules. Current intralogistic systems are quite customized with unique solutions and small production lots. In most cases these systems feature a central main control. To offer highly individual solutions, thus meeting the demand of shorter life cycles, there is a need for more flexible m...

knowledge of energyconsumption has many uses in industry. factors that are energy dependent have already been studied hence decision making on them are easier. energy demand studies of industry helps us to learn factors that are responsive to this demand. therefore planners can use these collected data in their decision making using the above factors. another use of energy demand can be used as...

flow regime in dam's bottom outlet is divided in pressurized flow and free surface flow by the gate located for discharge control. down stream tunnel involves high velocity multi component air –water flow studied by mathematical model. in this research work, we used finite volume mixture two phase flow model. because of high reynolds number, standard two equations k-e turbulence model was ...
