Research ArticleOpen accessEvery word in the titleThe Contamination Degree of Characteristic Fungi in Jet Fuel Detected by ATP BioluminescenceZezhen Li, Yun Xiong, Bo Chen, ZhenQiao MaAdenosine Triphosphate (ATP) lysate of the characteristic fungi in jet fuel was screened and three fluorescein-luciferase systems were compared in the paper. The correlation between ATP bioluminescence and traditional plate count for measuring the number of microorganism was also investigated and then a method of detecting the contamination degree of the characteristic fungi of jet fuel by ATP bioluminescence were … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 28 May 2018 · 10,519 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of the Application of Turbulence Models in the Calculation of Supersonic Gas JetIlina Ekaterina Evgenevna, Ilina Tamara Evgenevna, Bulat Pavel ViktorovichThis article considers the adequacy of the usage of various two-parameter differential turbulence models for the calculation of supersonic non-calculative (overexpanded and underexpanded) gas jet flowing into the environment that have a pressure equal to atmospheric. A brief historical background on the development of methods for calculating turbulent supersonic jet, which contain developed shock wave structures, is given. For each … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 7 Jan 2015 · 7,199 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleON THE RELIABILITY OF REYNOLDS-AVERAGED NAVIER STOKES PREDICTION OF MEAN FLOW CHARACTERISTICS OF A RECTANGULAR TURBULENT JET IN CROSSFLOWE. Khali, Y. F. YaoA jet of fluid discharging into a cross stream, also known as Jet In Crossflow (JICF), has received many experimental and numerical investigations. In addition to the fundamental understanding of three-dimensional mixing and shear flow characteristics, the fluid dynamics research community often regarded it as a benchmark test case for validating turbulence models. Although many authors considered the canonical case … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,958 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHomogeneous Bubbles during Jet Impingement QuenchingM. A. Islam, S. F. AhmedProblem statement: Jet impingement quenching has a very effective and large cooling potential and is a very effective means of cooling for many applications. It gives rise to heterogeneous and/or homogeneous nucleation of bubbles, which is yet to be explored. Approach: Analytically investigate the phenomenon that happened during a brief contact of a water jet impinging on a hot surface. … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,162 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Study of Flow Structures of Circular Pulsating Air JetRozli Zulkifli, Kamaruzzaman Sopian, Shahrir Abdullah, Mohd Sobri TakriffProblem Statement: Applications of impingement jets in industry for heating and cooling purposes requires a high convective heat transfer coefficient. Numerous studies have been conducted to improve the convective heat transfer coefficient for a steady impinging jet. A pulsating jet has a very high potential in replacing steady jet after it been found able to increase the heat transfer coefficients … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,778 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Relation Between Jet Stream Location and Cyclones Over the Western IranManuchehr Farajzadeh, Asadolah Khorany, Hassan LashkaryDaily rain data for the selected stations were obtained from the Meteorological Organization of Iran for the 1985-1999 period. The consecutive rain days of length 1 to 5 days and widespread over the study area were extracted. The jet tracks and speed surges were extracted from the daily weather maps of IRIMO for the 54 selected rainy periods. The results … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 6,814 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Pulsating Circular Hot Air Jet Frequencies on Local and Average Nusselt NumberRozli Zulkifli, Kamaruzzaman Sopian, Shahrir Abdullah, Mohd Sobri TakriffThe study was carried out to determine the effect of pulsating frequencies on the local and average heat transfer characteristic of a heated circular air jet. The velocity profile of a heated circular pulsating air jet was measured in the first part of the study. The same set-up was used to measure the heat flux of the pulsating jet impinging … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,500 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Simulation of 2_D Turbidity Currents and Wall JetM.H. Shojaeefard, K. Goudarzi, H. Ghasvari JahromiDense underflows are continuous currents, which move down the slope due to the fact that, their density are heavier than ambient water. In turbidity currents the density differences arises from suspended solids. Vicinity of the wall make density currents and wall jets similar in some sense but Variation of density cause this flows more complex than wall jets. An improved … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,034 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInflammatory Cytokine Expression Patterns in Rat Skin Exposed to JP-8 Jet FuelRandle M. Gallucci, Bethany M. MickleOne of the main complaints of personnel exposed to JP-8 jet fuel is irritant dermatitis.
