Sub-surface irrigation with porous clay pipe can be an efficient, water saving method of irrigation for many less developed arid and semi-arid regions. Maximizing the efficiency of clay pipe irrigation requires guidelines and criteria for system design and operation. In this study, experimental and simulated (with HYDRUS (2D/3D)) soil wetting patterns were investigated for sub-surface pipe syst...

This study aims to determine the effect of use 12 mm Netafim (NTF) pipe and ” pvc on a multilevel drip irrigation network, ability uniformity distribution polybag land. The test was carried out variations in tower water heights 220 cm, 120 cm 30 lateral pipe, data analysis (CU), volume at each network level. research conducted land area 1.5 m x 4 2 m, distance between level is 1 height 2.5 m. B...

Abstract The dynamic behaviors of a horizontal piping structure with an elbow due to the two-phase flow excitation are experimentally investigated. effects patterns and superficial velocities on pressure pulsations vibration responses evaluated in detail. A strong partition coupling algorithm is used calculate flow-induced (FIV) pipe, theoretical values agree well experimental results. It found...

Simulation analyses for in-situ cyclic loading tests in cohesive soil were conducted to indicate that finite element models considering nonlinearity of material , pile-soil separation and a loosened layer valid evaluating lateral resistance steel pipe piles with wings driven by rotational penetration. The results analytical studies demonstrated pile head load approached without when displacemen...

In this paper, we reported changes in the growth morphology of n+InAs nanowires (NWs) doped with Te which were selectively grown on nano-hole patterned InP(111)B substrates using an MOCVD method. While vertical InAs NWs <111> direction was extremely suppressed, their lateral enhanced when diethyl-tellurium (DETe) flow rate increased as they grew. Moreover, sidewall planes evolved from (11...
