Preparation and evaluation of properties of cast metallic foams with regular inner structure [PDF]

open access: yes, 2017
Lately we encounter still more new applications of metallic foams, as well as possible methods of their manufacture. These metallic materials have specific properties, such as large rigidity at low density, in some cases high thermal conductivity ...

Thermo-mechanical recycling of rubber: Relationship between material properties and specific mechanical energy [PDF]

open access: yesJournal of Materials Processing Technology, 2018
The studied and optimized devulcanization process is known as " High Shear Mixing " (HSM) recycling process. In the process the rubber is sheared between two metallic cones with special geometries. One cone is static as the other one rotates simultaneously and applies pressure to the material.

Quantum theory for parametric interactions of light and hypersound [PDF]

open access: yes, 1965
The problem of energy exchange between two electro-magnetic modes of different frequencies and an acoustic mode is formulated and solved. The results of the quantum mechanical analysis are also analyzed in classical terms and are found to be consistent ...

Physicochemical and sensory characterization of an extruded product from blue maize meal and orange bagasse using the response surface methodology

open access: yesCyTA - Journal of Food, 2018
The mixtures of blue cornmeal and orange bagasse were processed in a single screw laboratory extruder. We used an experimental design, central composite rotatable, where the factors were as follows: extruder die temperature (153–187°C), feed moisture ...

Characterization of cassava starch processed in an internal mixer

open access: yesPolímeros, 2013
An internal mixer connected to a torque rheometer was used to investigate the effect of moisture content (13.2 to 46.8 g.100g- 1), rotation speed (13.2 to 46.8 rpm) and processing temperature (53.2 to 86.8 °C), applying a factorial central composite ...

In-line Measurement of the Viscous Behaviour of Wheat Starch During Extrusion. Application to Starch Cationisation

open access: yesApplied Rheology, 2007
A specific twin channel slit die was used to measure in-line the viscous behaviour of an extruded wheat starch. This allows to put in evidence the influences of temperature, water content and specific mechanical energy (SME). The proposed rheological law

Accurate Calculation Method for Mechanical Specific Energy of Horizontal Well

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The existing drilling efficiency-monitoring model based on the theory of mechanical specific energy is only applicable to vertical wells. When it is used to monitor the drilling efficiency of horizontal wells, the impact of high friction in horizontal wells is not considered, so the monitored specific energy of the machine is ...
