in the present work the effect of cu-water nanofluid, as heat transfer fluid, on the performance of a parabolic solar collector was studied numerically. the temperature field, thermal efficiency, mean-outlet temperatures have been evaluated and compared for the conventional parabolic collectors and nanofluid based collectors. further, the effect of various parameters such as fluid velocity, vol...

The seasonal thermal energy storage technology for domestic heating applications is not enjoying the same increasing market penetration as the smaller diurnal thermal energy storage technology. Although high efficiencies are to expect with seasonal thermal energy storages, high up-front costs are likely to constitute an efficient market barrier, impeding the growth of this technology. This pape...

The main problem today is the shortage of energy and environmental pollution. These problems can be avoided by employing renewable energy schemes. The most common renewable energy resources include Wind Energy, Tide Energy, Solar Energy, Hydrogen Energy, Bio Energy, Terrestrial Heat Energy and Thermal Energy and so on. Pakistan is affluent in almost all these resources especially in Thermal Ene...

in recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. the hybrid system presented in this article produced power with sofc and stirling engine. the purpose is to analyze a 50 kw solid oxide fuel cell that could produce enough thermal energy for a 10 kw stirling engine working in the hybrid s...

hydrogen technology is becoming ever more relevant because hydrogen use can help containinggreenhouse gas emission if co2 capture and storage techniques are implemented in the hydrogen productiontechnology (when hydrogen is produced from fossil fuels). for this reason this work aims at carryingout a comparative analysis of possible energy scenarios in urban districts: a medium-small italian cit...

2014 The present paper reviews the problem of short term thermal energy storage for low temperature solar heating applications. The techniques of sensible and latent heat storage are discussed, with particular emphasis on the latter. Requirements for hot water storage subsystems are provided and the importance of stratification in hot water storage tanks is described. Concerning latent heat sto...

In manufacturing, thermal spray technology encompasses a group of coating processes that provide functional surfaces to improve the performance of the components and protect them from corrosion, wear, heat and other failings. Many types and forms of feedstock can be thermal sprayed, and each requires different process conditions and life cycle preparations. The required thermal energy is genera...

Smart applications of the Internet of Things are improving the performance of buildings, reducing energy demand. Local and smart networks, soft computing methodologies, machine intelligence algorithms and pervasive sensors are some of the basics of energy optimization strategies developed for the benefit of environmental sustainability and user comfort. This work presents a distributed sensor-p...

The integration of renewable wind and pumped storage with thermal power generation allows for dispatch of wind energy by generation companies (GENCOs) interested in participation in energy and ancillary services markets. However, to realize the maximum economic profit, optimal coordination and accounting for reduction in cost for environmental emission is necessary. The goal of this study is to...

Introduction: Recently head and neck cancer has pay attention to many researchers. Its therapeutic methods include surgery, chemotherapy, radiotherapy and Boron neutron capture therapy (BNCT). BNCT is better than conventional radiotherapy because it targets the tumor cell. This method involves two steps of infusion of stable 10B and then neutron radiation with a suitable intens...
