Abstract

Purpose

There are many differences in, and various opinions on, naming library education institutions around the world. In a number of countries, this diversity has increased a powerful trend among library professionals to discuss and to challenge the problem of naming schools in which they are studying the discipline and the programs by which they are being taught. The present study, in response to this trend, aims to find out an adequate answer to this problem based on the real state of the librarianship's educational institutions on the World Wide Web.

Design/methodology/approach

After an introductory note, various opinions are classified into two categories. The diversity in interpretation of renaming schools is reviewed chronologically. The survey was done and a sufficient conclusion was presented.

Findings

More than 98.5 percent of the schools have renewed their titles, while fewer than 45 percent have changed their titles completely from the traditional forms to the newer ones.

Research limitations/implications

Relativeness of the industrialization concept is too much. Therefore, conceptualization for such research would usually be a big problem.

Practical implications

It was not possible to discover whether the titles of the schools were being changed when the survey was being done or not.

Originality/value

The results of this survey can solve the paradox of renaming schools.

Abstract

Purpose

This paper aims to provide an experimental/numerical analysis of free convection within a hollow/finned cavity.

Design/methodology/approach

The hollow square cavity is equipped with eight active fins which have a similar configuration and different temperatures. Furthermore, four different thermal arrangements are considered to determine the order of temperature for each fin. The coupled lattice Boltzmann method is used, which not only maintains the considerable advantages of standard lattice Boltzmann method such as accuracy but also enhances the stability of this method.

Findings

The cavity is filled with TiO2-SiO2/Water-Ethylene Glycol nanofluid. The thermal conductivity and dynamic viscosity of nanofluid are experimentally measured using high-precision devices in six concentrations of the nanoparticle. In this study, some main parameters, including a range of Rayleigh number (103 < Ra < 106), the concentration of nanofluid (0.5 to 3 Vol.%) and thermal arrangements of fins, are considered. The effects of these main parameters on the flow, isotherms, heat transfer performance and entropy generation are studied.

Originality/value

The originality of this paper is combining the numerical simulation (lattice Boltzmann method) using a modern approach with experimental observations of nanofluid’s properties.
