Soret and dufour effects on mixed convection unsteady MHd boundary layer flow over stretching sheet in porous medium with chemically reactive species

引用

Applied Mathematics and Mechanics(English Edition) 2014年第7期35卷 849-862页

作者： A.nayak S.PANdA d.K.PHUKAN Silicon Institute of Technology Bhubaneswar 751024 India department of Mathematics National Institute of Technology Calicut 673601 India department of Mathematics Moran College Moranhat Assam 785670 India

This paper studies the thermal-diffusion and diffusion thermo-effects in the hydro-magnetic unsteady flow by a mixed convection boundary layer past an imperme- able vertical stretching sheet in a porous medium in the presence of chemical reaction. The velocity of t^he stretching surface, the surface temperature, and the concentration are assumed to vary linearly with the distance along the surface. The governing partial differential equations are transformed into self-similar unsteady equations using similarity transformations .and solved numerically by the Runge-Kutta fourth order scheme in as- sociation with the shooting method for the whole transient domain from the initial state to the final steady state flow. Numerical results for the velocity, the temperature, the concentration, the skin friction, and the Nusselt and Sherwood numbers are shown graph- ically for various flow parameters. The results reveal that there is a smooth transition of flow from unsteady state to the final steady state. A special case of our results is in good agreement with an earlier published work.

Effectiveness of state incentives for promoting wind energy： A panel data examination

引用

Frontiers in Energy 2015年第3期9卷 247-258页

作者： deepak SANGROYA Jogendra nayak department of Management Studies Indian Institute of Technology IIT Roorkee Roorkee 247667 India

Over the last decade, India has started to concentrate earnestly on renewable energy. The Indian government, as well as different state governments, are adopting policy instruments such as feed in tariff, captive consumption, renewable purchase obligation and genera- tion based incentive etc. aimed at renewable energy development. This paper evaluates the effectiveness of state level incentives for the development of wind energy in India. Fixed effect panel data modelling technique of econometric analysis is used to analyse the data of 26 Indian states in 11 years. The results show that feed in tariff and captive consumption are the significant predictors of wind energy development. However, renewable purchase obligation does not affect wind energy significantly.
