A containment spray system is used to mitigate the source term from building environment as part of severe accident management actions. Tellurium one volatile fission products and many tellurium isotopes decay into iodine, which causes a threat public due its radiotoxicity build-up in thyroid gland. The removal efficiency model against species formed under conditions was investigated with exper...

An understanding of the physical mechanisms underlying the atomization process from a spray device can reveal important information leading to more effective device design. A commercial nasal spray device exhibiting low pressure atomization was tested to obtain spray formation, its characteristics, droplet size distribution, and droplet velocity. High speed laser photography combined with an in...

In order to master effectiveness situation of underground coal mine spray and dust reduction, analyze and improve the process of spray and dust reduction which effect is non-ideal, feasibility of introducing process capability analysis as scientific management method was investigated. Measuring tool was analyzed with measurement system analysis which guaranteed accuracy and precision of measure...

Field measurements of spray drift are usually carried out by passive collectors and tracers. However, these methods are labour- and time-intensive and only provide point- and time-integrated measurements. Unlike these methods, the light detection and ranging (lidar) technique allows real-time measurements, obtaining information with temporal and spatial resolution. Recently, the authors have de...

A distributed dynamic model was built using gPROMS 2.3.7 language for an integrated Process including a cogeneration system, a plate heat exchangers set and a salt recrystallization process. It was analyzed the effect of a simulated spray system model on the integrated process, by comparing the global performance of the system with and without sprays. Due to air drift issues, quasi-random time ...

The transport of droplets in a pressure-atomized kerosene spray flame was examined using a twocomponent phase Doppler system to measure the droplet size and velocity distributions at several locations within the spray. The effect of combustion on droplet transport was examined by comparing the results to a nonburning spray under similar flow conditions. Directions of motion of droplets are calc...

Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...
