In this paper, A single-bed finned tube adsorption refrigeration system model was established to compare the characteristics of three metal organic framework materials(MIL-101(Cr), MIL-101(Cr)/CaCl2-10%, MIL-101(Cr)/ CaCl2-20%).The change material properties under different thickness/length/number fins characterized, and most suitable bed structure for materials obtained.Theresults show that nu...

We propose a two-phase model having a Newtonian rheology for the fluid phase and friction for the particle phase to describe bed-load transport in laminar pipe flows. This model is able to provide a description of the flow of the mobile granular layer. When the flow is not significantly perturbed, simple analytical results of the particle flux varying cubically with the Shields number can be ob...

AIMS The aim of this study was to ascertain the average height of occupied patient beds in a general medical ward and to investigate the relationship between staff working-height for patient beds, time and whether the patient was on fall precaution. BACKGROUND The height of occupied patient beds can be an overlooked contributor to inpatient falls. Better physical design of hospital equipment ...

in order to study the effects of planting pattern on yield and yield components in different cultivars of forage corn (zea mays l.), an experiment was conducted at saline conditions (ec=6.43 ds.m-1) of dasht-e-malhe, neyshabour during growing season of 2009-2010. nine treatments and two furrow planting and furrow bed planting as main plots and three cultivars (ksc 704, zp 644 and ns540) as sub ...

The transient preheating process of a regenerative oxidation bed placed in a coal mine methane thermal reverse-flow reactor is numerically investigated in this paper. The regenerative oxidation bed is heated by the burned gas which is generated from a burner and is distributed through manifolds, which is modeled in a three-dimensional, unsteady state and laminar flow system, and is assumed as a...

Spirals as internals are utilized to reduce the axial mixing of solids in fluidized beds, by routing the solids flow in a predetermined route or by localizing the solids mixing. The drying kinetics of continuous fluidized bed with and without internals has been compared and modeled using batch drying kinetics and residence time distribution analysis. The batch drying experiments were conducted ...

The sorption of thorium and uranium ions by functionalized SBA–15 mesoporous silica materials with Schiff base ligating groups N–propylsalicylaldimine (SBA/SA) and ethylenediaminepropylesalicylaldimine (SBA/EnSA) from aqueous solution was investigated in fixed-bed column method. The TEMPeffect of pH, sample solution volume, and the column design parameters such as sample and eluent flow rat...

The H2020-project OPTIMA concept of smart sprayer relies on several functionalities, including variable nozzle spacing for bed-grown carrots, based an air-assisted boom sprayer. A prototype was designed and evaluated though canopy deposition, ground losses, spray drift potential. Four bed configurations, various types, angles, sizes (XR8004, combination AIUB8504/AI11004, AI8004, XR8002) at the ...
