The Impact of Consumer Currency Perception on Price Sensitivity
This paper is concerned with the effects of flow and migration of nanoparticles on heat transfer ... more This paper is concerned with the effects of flow and migration of nanoparticles on heat transfer in a straight channel occupied with a porous medium. Investigation of forced convective heat transfer of nanofluids in a porous channel has not been considered completely in the literature and this challenge is generally considered to be an open research topic that may require more study. The fully-developed flow and steady Darcy-Brinkman equation is employed in the porous channel. The local thermal non-equilibrium model is assumed between the pure fluid, solid and the nanoparticle phases. It is assumed that the nanoparticles are distributed nonuniformly inside the channel. As a result, the volume fraction distribution equation is also coupled with governing equations. The effects of Lewis number, Schmidt number and modified diffusivity ratio (N bt ) on the heat transfer are completely studied. The results show that the non-dimensional heat flux absorbed by fluid is decreased when the Lewis number is increased. This behaviour can also be observed in the heat flux absorbed by the particles and the solid. The effects of Scmith number, Lewis number and N bt on the volume fraction distribution and the heat flux are also studied numerically. The results indicate that when the Schmith number is increased the particle distribution tend to the entrance distribution. The effect of N bt on the heat flux and the volume fraction is studied and discussed as well.

Experimental Investigation of Forced Convection of Nanofluids in a Horizontal Tube Filled with Porous medium

Investigation of force convective heat transfer of nanofluids in a porous pipe with uniform wall temperature has not been considered completely in the literature. In this experimental study, Alumina nanofluids with different volume fractions have been completely employed. By measuring the nanofluid temperatures, the Nusslet numbers have been reported as a function of the Reynolds number. Also, the pressure drop of nanofluids inside the porous pipe has been measured. The accuracy of the experimental results has been also validated by the presented theoretical formulas in the literature. The result shows a considerable increase in the Nusslet number by using nanofluids instead of water. Convective heat transfer of a porous pipe has been also studied as a novel method to increase the heat transfer rate. The related results show...

Heat Transfer Enhancement in a Channel Partially Filled with a Porous Block: Lattice Boltzmann Method

Combined pore level simulation of flow and heat transfer is performed for a 2D channel which is partially filled with square obstacles in both ordered and random arrangements by LBM which is not studied completely in the literature. The effect of the Reynolds number, different arrangements of obstacles, blockage ratio and porosity on the velocity and temperature profiles inside the porous region are studied. The local and averaged Nusselt numbers on the channel walls along with the respective confidence interval and comparison between results of regular and random arrangements are presented for the first time. For constant porosity and block size, the maximum value of averaged Nusselt number in the porous block is obtained in the case of random arrangement of obstacles. Also, by decreasing the porosity, the value of averaged Nusselt number is increased. Heat transfer to the working fluids increases significantly by increasing the blockage ratio. Several blockage ratios with different arrangements are checked to obtain a correlation for the Nusselt number.
Price plays a significant role in product quality in today communities, and consumers may not be ... more Price plays a significant role in product quality in today communities, and consumers may not be aware of the quality and characteristics of the products they buy, despite of presence of distinctive products. They often are not able to compare different brands in terms of the quality. Although many studies on price-quality relationship support this common belief, some other studies indicate that this relationship depends on the specific type of the product, and overall presence of such relationship is less probable. Current work aims at investigating the relationship between product price and purchaser perception of the quality in durable, less durable and non-durable products in Kish Island's markets as a case study. Three selected products include: LED TV as a durable product, t-shirts as a semi-durable product, and toothpaste as a non-durable product. Research tool is a questionnaire and collected data are analyzed using SPSS V.19 software. Results of the research indicate that price is one of factors reflecting the quality. It was true about t-shirt more than two other products.

There are limited studies about the role of neuropeptide Y in febrile seizures. This study was conducted to evaluate the association between plasma neuropeptide Y level and febrile seizures in children. Seventy six patients with typical and atypical febrile seizures (each group 38 patients) and 38 sex and age matched control subjects were enrolled. The mean plasma levels of neuropeptide Y in typical and atypical febrile seizures were 90.60±28.01 and 97.34±41.27 pmol/l respectively. This value in control group was 88.94±32.66 pmol/l. There was no significant differences between groups regarding plasma neuropeptide Y level (P=0.532). Also, there was no significant difference in comparison with case groups (P=0.40). This study revealed that there is no association between plasma neuropeptide Y and febrile seizures.
