“…It includes two wall terms but no production term. Prasad and Malan (1998) pointed out that this model is sensitive to the free stream value of l and results in significant overprediction of the spreading rates of most freeshear flows. However, the k7l model is still used in Office National d'Etudes et Recherches Ae´rospatiales (ONERA) with a shear stress (SST) limiter (Aupoix 2007) because the original k7l model fails to predict separated flows.…”

In this study, the classical eddy viscosity turbulence models are analysed from a new standpoint. Based on this standpoint, a new, two-equation k À ffiffiffi ffi o p model that aims at separated flows is presented. This new turbulence model is directly derived from the standard k7e and k7o models and tested against flow in a plane, asymmetric diffuser and against NACA 4412 aerofoil flow. The results of numerical simulation of the two different types of flow compared to experimental data show that the new k À ffiffiffi ffi o p model is good at prediction of separated flows. The results are very encouraging, but further verification and extensive application of this new model are needed.

“…Previous researchers Balusamy et al, [3], Kumar et l., [4], Sodhro et al, [5], Kumar et al, [6] and Rahmani et al, [7] aimed to synergize human, data, processes, organizations, services and facilities together in exceptional ways. Thus, to attain the target of sustainable development, plans are being developed locally and internationally keeping in mind the environmental, social and economic aspects to propose for Green Internet of Things (G-IoT) [8].…”

The development of the Internet of Things and their integration in smart cities have changed the way society work and live. Green IoT evolves around by designing, leveraging and enabling technology to support and achieve sustainable development. Hence, this study highlights on greening IoT towards a sustainable smart living. Main aim is to embed Bluetooth into Green IoT controlled device. This project in this study is named as Green IoT Bluetooth Hotmeal Container (GIoT-BHMC) which satisfies energy saving, cost effectivity, supports smart industries and smart living. The idea is reheating food using Bluetooth technology and rechargeable AA batteries installed in a food container yet rejecting the use of electricity. Reheat process is controlled by mobile application developed in an android environment. Four phases allocated for this study consisting of planning for design, development of device with Bluetooth technology, integration and testing phase and finally the implementation phase. User acceptance test was conducted too to ensure study findings meet users’ requirements. Study contributes to energy efficiency, sustainability on smart living and green metrics. To-date, GIoT plays crucial role in making a better-off citizen. In specific, efficient resource utilization, sustainability, reducing energy consumption, pollution, and e-waste are the main idea of greening the technology. This study is a practical insight towards eco-friendly and sustainable city based on emerging GIoT technologies.
