In this paper, turbulent forced convection flow of water–Al2O3 nanofluid in a circular tube, subjected to a constant and uniform heat flux at the wall, is numerically analyzed. Two different approaches are taken into account: single and two-phase models, with particle diameter equal to 38 nm. It is observed that convective heat transfer...

In this article, developing turbulent forced convection flow of a water-Al2O3 nanofluid in a square tube, subjected to constant and uniform wall heat flux, is numerically investigated. The mixture model is employed to simulate the nanofluid flow and the investigation is accomplished for particles size equal to 38 nm. An entropy generation...

The influence of economic and demographic variables on the annual electricity consumption in Italy has been investigated with the intention to develop a long-term consumption forecasting model. The time period considered for the historical data is from 1970 to 2007. Different regression models were developed, using historical electricity...

A parametric investigation of entropy generation of nanofluid turbulent forced convection inside a circular section tube subjected to constant wall heat flux is presented. The analysis is developed for different inlet conditions (i.e. constant Re, fixed mass flow rate and constant velocity) and in a concentration range from 0% up to 6%. The...

The present paper proposes an analysis based on the second principle of thermodynamics applied to a water-Al2O3 nanofluid.The nanofluid flows inside a circular section tube subjected to constant wall temperature.The aim of the investigation is to understand, by means of an analytical model, how entropy generation within the tube varies if inlet...

The present paper reports a numerical investigation of a forced convection water flow within a two-dimensional ribbed channel. A uniform heat flux is applied on the external walls. The flow regime is turbulent and Reynolds numbers are in the range 10·10^3÷100·10^3. Square and chamfered rib shapes with different arrangements are analyzed in...

The influence of economic and demographic variables on the annual electricity consumption in Italy has been investigated in order to develop a simple and data light electricity consumption forecasting model, to be used as part of more complex planning tools. The time period considered for the historical data is from 1970–2007. Multiple and...
