Abstract The objective of this study was to investigate the influence nanofluid concentration on heat transfer rate radiator pipes. This used computational fluid dynamics simulation method ANSYS Fluid Flow Fluent software. working in prepared Al 2 O 3 and H mixture. Simulation performed at various nanoparticles ranging from 0 1%. velocity inlet temperature were set 0.4 m/s 130°C, respectively. ...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
OBJECTIVE To determine if bladder outlet obstruction can be adequately relieved after laser prostatectomy. PATIENTS AND METHODS Since November 1992, a total of 105 patients underwent laser treatment of the prostate because of complaints related to benign prostatic enlargement (BPE). To date, urodynamic data from a study of pressure flow analysis are available for 79 patients both at baseline ...
The location of heat transfer pinch point in evaporator is the base of determining operating parameters of organic Rankine cycle (ORC). The physical mathematical model seeking the location of pinch point is established, by which, the temperature variations both of heat source and working fluid with UA can be obtained. Taking heat source with inlet temperature of 160 C as example, the matching p...
The application of personalized ventilation systems, particularly in the buildings, is one of the new topics that today presented to it, because of their proper performance in reducing energy consumption and creating better thermal comfort conditions. In the current study, the energy consumption of a personalized cooling system installed in a room, considering the constraint of thermal comfort,...
This paper proposes a control strategy for a Diesel Oxidation Catalyst (DOC) which is grounded on a one-dimensional distributed parameter model. This first principles model for the propagation of the temperature variations accounts for spatially distributed heat generation (due to oxidation of reductants). As is discussed, heat generation can be regarded as equivalent inlet temperature variatio...
Original scientific paper Numerical simulations of four combustion processes in a dual-fuel combustor of chemically recuperated gas turbine (CRGT) were carried out in this work. The fuels in the four combustion processes were liquid fuel, liquid fuel + steam, liquid fuel + reformed gas and reformed gas, respectively. The mathematical models adopted for different fuels combustion consist of real...
The fluid flow and heat transfer in a three-dimensional microchannel filled with Al2O3- water nanofluid is numerically investigated. The hybrid scheme is used to discretize the convection terms and SIMPLER algorithm is adopted to couple the velocity and pressure field in the momentum equations. The temperature fields, variation of horizontal velocity along the centre line of the channel, a...
Experiments were performed to determine the effect of community composition on system function (bacterial production) in arctic Alaska. In this system bacterial production is controlled by: community, temperature, nutrients, and carbon source. Lake inlet and outlet communities in these experiments were different in composition, based on PCR-DGGE fingerprinting of 16S rDNA. For both communities,...
