Atmospheric water harvesting (AWH) devices represent a fruitful hope to cope with the shortage problem throughout world.The vast development in AWH technology and wide spread of various techniques will largely contribute implementation machines different household, agricultural industrial applications.In last decades, huge amount research has been done on methods amazing differences results that mislead readers even researchers.In this study, theoretical developments, market were reviewed.A...
This study goes on the enhancement of thermal performance a chimney type electrically heated hot storage tanks (HST) in static mode.The different natural circulation areas (chimney areas) were used with diameter large (9.5 cm), medium (2.5 cm) and small (1.5 to find effect HST performance.Being part real system, insulated without insulation was also studied.The experiments showed that significantly affects stratification within tank.Different contact diameters cm, 2.5 cm 1.5 tested giving...
Disasters, extreme weather conditions and rural recreation makes the availability of a portable heating cooling device as must. There are many devices that work on power generation in market. The air-conditioner which works heat pump principle is well known. Harsh conditions, natural disasters areas (deserts mountains) requires available fuel has low consumption rate. Such will help saving lives encourage tourism. In this paper, proposed for places, harsh where no electricity available....
Liquid-gas flows in pipelines appear many industrial processes, e.g. the nuclear, mining, and oil industry.The gamma-absorption technique is one of methods that can be successfully applied to study such flows.This paper presents use method determine water-air flow parameters a horizontal pipeline.Three types were studied this work: plug, transitional plug-bubble, bubble one.In research, radiometric set consisting two Am-241 sources NaI(TI) scintillation detectors have been applied.Based on...
The subject matter of the article concerns velocities/flow rate measurements in area disturbed flows-behind 90° bend. They were conducted by means an ultrasonic flowmeter with clamp-on sensors on pipeline, for water and two different Reynolds numbers 70,000 100,000, corresponding to velocities approximately 1.42 m/s 2.04 m/s. tests carried out at 12 distances from disturbance. Sensors circumference pipeline mounted 30° each. correction factor values calculated given measurement geometry....
The aim of this work is to experimentally determine and evaluate the value correction factor for ultrasonic flow meters in order improve their accuracy. This article concerns velocity measurement with use an meter area disturbed behind distorting element. Clamp-on are popular among technologies due high accuracy easy, non-invasive installation, because sensors mounted directly on outer surface pipe. In industrial applications, installation space usually limited and, therefore, frequently...
The control of the rigidity bumper can be provided by an application magneto-active elastomers (MAE), capable to change their properties in a reversible and fast manner under action applied magnetic field. dependence energy taken away at impact on variable weight has been found taking into account presence controllable MAE elements construction. calculated fields pressure deformations are necessary for optimization design, form material forward panel bumper.
This research proposed an integrated eco-system for conditioning outdoor public area (park or sport) in a hothumid environment.It is accomplished by the use of dehumidifier control machine driven renewable solar power; after which air distributed throughout ducting system.The system will harvest moisture from air, utilize it drinking water production and plants irrigation as well deliver low temperature, humidity ratio controlling results comfortable relative temperature (24 °C, 50% RH).The...
This article discusses an ultrasonic technique for monitoring liquid flow. The mean velocity of the flow behind obstruction in throttle type was measured using meter. Furthermore, equations used to analyze distribution a distorted turbulent are presented. measurement findings were compared with those separate models select best equation characterizing Measurements taken two distinct settings by varying distance from and angle flowmeter head position. measurements performed determine order...
The aim of this study was to improve the residential photovoltaic systems (RPVS) sector, using surveys as research method.The carried out in four selected districts Jordan, taking into account largest population.The prepared sets questionnaires covered a wide range topics, divided three parts and seven sections.The results showed that highest use solar energy for heating Amman district, while Irbid Zarqa (PV) system installations can potentially be more prospective because high electricity...
One of the most important challenges in fluid mechanics, gas dynamics, and hydraulic machinery fields is measuring flow velocity with high accuracy. It more large systems; such as thermal power stations, scale generations, combined cycle plants. The exact estimation measurement uncertainty inflow extremely evaluating accuracy measurement. This work describes problem estimating when there are two or dominant components budget. . Two methods, analytical numerical methods used to study...
Thermal comfort in openair situations is a difficult industrial task.In literature there were insufficient studies on how to control the external microclimate region, and are many activities outside house open areas that require temperature control, such as stadiums hot humid countries, tourism, recreational climates.Openair conditioning requires huge amount of energy, negatively affects global warming earth.To reduce energy consumption proposed.Isolation controlled area performed...
The article presents an example of thermal-flow analysis the bottom ash cooler cooperating with circulating fluidized bed boiler. There is presented a mathematical model series-parallel hydraulic system supplying in cooling water. numerical calculations indicate influence changes pipeline geometrical parameters on water flow rate system.

This study investigates the impact of changes in velocity profiles on measurement inaccuracies gas flow streams detected by an ultrasonic flowmeter. The cross-sectional profile was influenced downhill rate, causing variations shape factor coefficient. flowmeter processing equation should consider coefficient variations. Consideration for these can result errors stream. assumes a single, constant value coefficient, which lead to inaccuracies. article covers transit-time caused change flowing...
