furrow irrigation is the most common type of surface irrigation. determine the advance and recession time in the field is required the accurate measurement and this can be costly and time consuming. winsrfr model is used for simulation furrow irrigation by zero inertia and kinematic wave engines. using this model, advance time, reaction time, infiltration depth, runoff depth and application eff...

In order to avoid environmental pollution and eliminate the need for using fertiliser, this study assessed for the first time the optimum performance of mature (in operation since 2011) vertical flow constructed wetlands in treating domestic wastewater (with and without hydrocarbon) and the subsequent recycling of the outflow to irrigate chillies (De Cayenne; Capsicum annuum (Linnaeus) Longum G...

High order fast sweeping methods have been developed recently in the literature to solve static Hamilton-Jacobi equations efficiently. Comparing with the first order fast sweeping methods, the high order fast sweeping methods are more accurate, but they often require additional numerical boundary treatment for several grid points near the boundary because of the wider numerical stencil. It is p...

The article presents results of numerical and experimental analyses a tube-and-fin heat exchanger. numerous studies performed so far have proved that non-uniform inflow mediums in such exchangers may significantly affect their performance. aim the presented this is to investigate impact but controlled air on double-row exchanger was first modeled numerically determine its output at uniform medi...

In this study lake levels of Lake Tana are simulated at daily time step by solving the water balance for all inflow and outflow processes. Since nearly 62% of the Lake Tana basin area is ungauged a regionalisation procedure is applied to estimate lake inflows from ungauged catchments. The procedure combines automated multi-objective calibration of a simple conceptual model and multiple regressi...

Methods We compared SSFP four chamber view images (20 phases per cycle protocol) between 11 surgically-confirmed CP patients and 11 controls. We deconvoluted the mechanics of the septal bounce and correlated it with periods of the cardiac cycle. To demonstrate that the septal bounce is caused by the interaction between the tricuspid inflow and septum we constructed a parameter called the septal...

Parallel compressor theory (PCT) is commonly used to estimate effects of inlet distortion on performance. As well as compressor, the actual inflow pump also nonuniform and unfavorable for performances. Nowadays, insufficient understanding performance restricts its development. Therefore, this paper applies PCT predict external characteristics evaluate internal flow instability waterjet under in...

The purpose of the present study is to investigate and analyze numerically, the effective mechanisms on the flow field and pollutant dispersion around a simple and long street canyon by means of Large Eddy Simulation (LES) approach using various inflow turbulence generation methods. For this purpose, four methods i.e. vortex, mapping, synthetic and no-inlet perturbation methods are used as infl...
