An experimental and numerical investigation of the flow in a compressor duct with engine-realistic in-production features is presented in this paper. The experimental testing was conducted in the ND-FSCC test facility at University of Notre Dame, Indiana, USA. A baseline duct was also tested for back-to-back comparison. The ducts were heavily instrumented; duct inlet and exit flowfields were scanned using a five-hole pressure probe that provided total pressure, velocities and flow angles. Based on the five-hole probe total pressures, duct losses could be assessed. Furthermore the duct inlet boundary layers were traversed and turbulence intensity levels were assessed. For the CFD analysis of the production-like duct, a highly complex computational grid, resolving all the geometrical features present, was used. A previously validated surface roughness model was used to account for the cast aero-surfaces. Both experimental and numerical results show that there is a significant increase in loss for the production-like duct when compared to the baseline duct loss. The CFD results agree very well with experimental results for the baseline duct, which makes it possible to use the experimental data recorded for the production-like duct to validate CFD tools for real geometry effects, such as interface steps and surface roughness for example.

Abstract Currently the natural materials become popular building material for houses, buildings and recreational property. The risk of fires in residential timber construction or eco houses cannot be completely ruled out, therefore there is a need for proper and correct implementing preventive measures and application of all available solutions, which may reduce the risk of fire as far as possible, to slow down the combustion process, to protect the life of people, animals and also the building itself until arrival members of the Fire and Rescue Services. Fireproofing of combustible materials is a specific area of fire protection. For scientific research as well as for real-life practice, not only their structural and physical properties, but also fire-technical characteristics are really important. The present researchers mostly focus on fire-retardant treatment of wood that is why the authors of this contribution focused on a different combustible material. This research article presents the experimental testing and examination of the reaction to fire test of the selected thermal insulation of hemp fiber that was impregnated by the selected fire retardant in laboratory conditions.

Swelling Soil

swelling soils exist in many developing urban regions in egypt. Most of these urban regions have new huge developments under constructions. The structures constructed on these swelling soils may be exposed to high damage if any significant change in the moisture content of these swelling soils occures, so the presence of such swelling soils represents a significant hazard. Investigation the behaviour of these swelling soils as well as determination of their swelling parameters has become highly necessary. In this paper, intensive experimental testing program has been conducted on some soil samples collected from some of these regions to determine their swelling parameters. Through this experimental testing program, oedometer swell test has been firstly conducted on same soil with two different techniques; namely different pressure method and huder-amberg method. The procedures and obtained results of the two used methods are discussed and compared showing advantages and shortages of each method. After that, all subsequent experimental tests were perfomred using huderamberg method as it demonstrated high superiority in determining swelling parameters. Grob’s 1d swelling law was applied to all obtained experimental results to give exact and complete determination for all swelling parameters. Furthermore, swelling soil has been simulated numerically via the new userdefined swelling constitutive model which has been recently implemented for the finite element software plaxis. The suitability of this model to simulate the performance of swelling soil is verified by conducting a numerical simulation to one of the huder-amberg oedometer tests through the oedometer soil test facility available in plaxis software. Finally, based on the aboveselected experimental approach, swelling parameters were determined from the experimental tests conducted on different soil samples collected from some selected arid/semi-arid regions in egypt. Such test results were summarized and presented as a useful key-parameters of these swelling soils which can be used as pre-determined inputs in any further numerical analyses.

In the current digital era, information is a basis of some systems. In the area of information, great emphasis is also placed on its security and possibilities of use. The basis of the alarm transmission system is information about the protected object, which is transmitted to the remote center of the alarm transmission system. Operators of alarm transmission system centers should be obliged to carry out regular testing of the availability of individual transmission networks. At present, there is a trend that those tests are carried out by telephone calls between the two technicians and the time of transmission of information is measured utilizing a stopwatch. To automate this process, a test facility has been created that can simulate and record the intrusion of a protected object. Initial experimental tests have ascertained whether it is possible, with the test equipment, to generate the data necessary to assess the reliability of alarm transmission systems.
