Air-lift-pump merupakan suatu rangkaian alat yang digunakan untuk memindahkan air dan campuran (berlumpur) dari tempat ke titik lain. Sistem kerja air-lift-pump melalui media pipa dengan cara menginjeksi udara pada saluran bawah terendam. Tekanan aerator akan mendorong bergerak atas menuju arah sama melewati pipa. Cairan kental atau lumpur dapat dinaikan menggunakan air-lift-pump. Gaya apung me...
Complex heat transfer phenomena (including unsteady state conduction, convection and solidification processes) occur in steel belt conveyer sulfur granulating method. Numerical simulation of this technique is performed via a comprehensive and multifaceted one dimensional model. Since the air situated between the adjacent sulfur pastilles is essentially stagnant, therefore, the surface tempe...
A one hour integrated flask sampling system to collect air in automated NOAA/ESRL 12-flask packages is described. The integrating compressor system uses a mass flow controller to regulate the flow of air through a 15 l volume, thus providing a mixture of air collected over an hourlong period. By beginning with a high flow rate of 3.8 standard liters per minute and gradually decreasing the flow ...
This study evaluated the use of a system that delivers a small field of local, directed air from a high-efficiency particulate air (HEPA) filter to reduce airborne particulate and airborne bacteria in the surgical field during total hip arthroplasty. Thirty-six patients were randomized into 3 groups: with directed air flow, with the directed air flow system present but turned off, and control. ...
This work proposes a novel market-based air traffic flow control model considering competitive airlines in air traffic network. In the flow model, an agent based framework for resources (link/time pair) pricing is described. Resource agent and auctioneer for groups of resources are also introduced to simulate the flow management in Air Traffic Control (ATC). Secondly, the distributed group pric...
