To investigate the influence law and mechanism of relative circumferential position intake struts on unsteady load vibration first stage rotor, 1.5-stage a heavy-duty gas turbine compressor with was numerically simulated. The analysis flow field rotor blade reveals that has little effect aerodynamic performance but obviously changes level blade. When strut inlet guide vane wakes coincide, they ...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
abstract: iran passed wide range of events over her controversies history. it has great special geopolitics position, natural resources and cultural values. iran is in asia and connects asia to europe. iran as relational bridge has an important role so that it could be an important center during first and second world war for enemies' forces in spite of explicit neuter declaration from ira...
Tillage system effect, Conventional (CT) vs. No-Till (NT), on soil physical properties and Br transport was studied at two locations in North Carolina. The soil types were a Typic Paleudults at Coastal Plain (site 1) and a Typic Kanhapludults at Piedmont (site 2). Bulk density (BD), total porosity (TP), macroporosity (MP), and saturated hydraulic conductivity (Ks) .were measured in plant row (R...
Background: Nutritional problems in premature newborns are of great importance for their development. In this regard, the neonatal positioning during and after feeding can have a significant effect on their nutritional tolerance. Therefore, the present study was conducted to compare the effect of two positions (i.e., prone and right lateral) on gastric residual volume ...
In this work, first the differential equation characterizing position vector of spacelike curve is obtained in Lorentzian plane $mathbb{L}^{2}.$ Then the special curves mentioned above are studied in Lorentzian plane $mathbb{L}%^{2}.$ Finally some characterizations of these special curves are given in $mathbb{L}^{2}.$
