AbstractNow a day’s variety of nanomaterials is available, among these Aluminum Alloys AA7072 and AA705 are significant due to their thermal, physical and mechanical characteristics. These extensively used in manufacturing of spacecraft, aircraft parts and building testing. Keeping in view the significance of nanoliquids, the analysis of methanol suspended by AA7072 and AA7075 alloys under the multiple physical flow conditions is reported. The model is successfully treated by coupling of RK and shooting algorithm and examined the results for the flow regimes by altering the ingrained physical parameters. Then physical interpretation of the results discussed comprehensively. To validate the analysis, a comparison between the presented and existing is reported under certain assumptions on the flow parameters. It is found that the results are reliable inline with existing once.

The use of condensed extract in the production of corn feed contributes to the improvement of their nutritional and biological value. The rheological properties of the feed material are of great importance in the mechanical interaction with the working bodies of the machines, in the movement of viscous media along technological conveyors, as well as in the intensification of heat exchange processes. The technique, laboratory equipment and the results of studies of physical and mechanical characteristics of corn feed are presented. The viscosity properties of the corn extract are investigated depending on the temperature. It is shown that when decreasing the temperature, the viscosity of the corn extract increases due to the aggregation of its components, which characterizes the non-Newtonian flow of the extract. The coefficient of external friction of the pulp and extract mixture in the technology of preparing corn feed allows calculating the geometry of the storage tanks and energy costs of the processes. The change in the coefficients of friction of corn feed when interacting with various surfaces, depending on the content of dry substances. The specific heat capacity, thermal conductivity and thermal diffusivity of the extract and corn feed were determined and investigated. It has been revealed that the dependences of the thermo-physical parameters of the extract and corn feed on the solids content are non-linear in nature, monotonously decreasing when increasing the concentration of solids.

Abstract The factors that influence the strength characteristics of rocks can be different in nature, being divided into external and internal factors. The mechanical properties of hard rocks are a result of geological, physical and chemical factors. In order to highlight the physical parameters that influence the strength characteristics of the rocks, in this paper there were analyzed six types of volcanic magmatic rocks such as andesites. In terms of stress behavior, rocks are directly influenced by their physical properties, such as volumetric density, porosity, compactness, moisture and the degree of alteration of mineral components. For this purpose, several sets of tests were performed to determine the physical and mechanical characteristics of the rocks, based on which it was possible to analyze how the physical parameters influence the strength characteristics.

Physical And Mechanical Characteristics

The problem of increasing the bearing capacity of the base is an relevant problem in modern geotechnical construction. When significant loads are transmitted to the base, the use of traditional technologies is not always justified. Often there is an urgent need to use non-standard ways to strengthen the bases. In many cases, the geotechnical situation is aggravated by the presence of weak underlying layers with unstable physical and mechanical characteristics in engineering-geological sections. When strengthening such bases with the help of traditional piles, the latter can get negative friction, which significantly reduces their bearing capacity on the ground, sometimes reaching zero values. This may lead to additional precipitations of the objects being constructed and constructed in the zone of geotechnical influence. The use of ERT piles in most cases successfully solves many complex geotechnical problems.
