Abstract: Parabolic concentrator mirrors are an important component of many solar energy systems, particularly solar mirror collectors. Precision parabolic mirrors are expensive to fabricate and to transport. ...

Abstract: Thermally conductive composites as compared to metals have reduced density, decreased oxidation, and improved chemical resistance, as well as adjustable properties to fit a given application. ...

Abstract: Laser repetitive pulse heating of the workpiece surfaces results in thermal stresses developed in the vicinity of the workpiece surface. In the present study, laser repetitive pulse heating with ...

Abstract: The service life of tooling plays an important part in the economics of the extrusion process. A number of causes are considered responsible for initiating damage to the dies before its ...

Abstract: We report on the strongly nonlinear dynamics of an array of weakly coupled, noncompressed, parallel granular chains subject to a local initial impulse. The motion of the granules in each chain is constrained to be in one ...

Abstract: Analytical solutions for temperature distribution, heat transfer rate, and fin efficiency and fin effectiveness are derived and presented for orthotropic two-dimensional pin fins subject to ...

Abstract: Mechanical damage in transportation pipelines is a threat to their structural integrity. Failure in oil and gas pipelines is catastrophic as it leads to personal fatalities, injuries, property ...

Abstract: Neutron imaging has been demonstrated to be a powerful tool to measure the in situ water content of commercial proton exchange membrane fuel cells (PEMFCs) in two and three dimensions. The ...

Abstract: For the repair of pipeline defects, repair sleeves are the most widely used method in petrochemical industry. The objective of this work was to optimize the thickness of nonpressure containing ...
