Kinetic studies and shrinking core model on solvolytic extraction of coal
(2000)The studies on the kinetics of solvent extraction of coal using Nmethyl 2 yrrolidone NMP, anthracene oil, and cetene have been performed separately. The extractionsrreactions were found to have first order rate law. The ... 
Load frequency control of isolated wind diesel hybrid power systems
(1997)In this paper, a load frequency controller is designed for isolated wind Diesel hybrid power systems, and its effect on the transient performance of the system is evaluated. The modelling of the system,consisting of a wind ... 
Loadfrequency control of isolated winddiesel microhydro hybrid power system(WDMHPS)
(1997)We examine loadfrequency control of isolated WDMHPS provided with conventional proportionalplusintegral controllers. The parameters of the controller are optimised for system performance with step or realistic disturbances ... 
Longterm comparative study of solardistiller systems
(1993)We show how the thermal losses within and outside a solar distillation unit vary with water depth in the basin of a passive solar still. The latent heat of vaporisation has been used for distillation under both passive and ... 
Losses in diagonal MHD generator
(1999)Losses in an MHD generator not only reduce the power output but also degrade it. The losses due to heat, friction and leakage through insulatingwall/slag have been analyzed for the diagonal generator for better control ... 
A low cost solar water heater suitable for rural, as well as urban areas, of vietnam
(1998)The builtinstorage type of solar water will be suitable for rural as well as urban areas of vietnam,in genral and the Hanoi region,particular(mainly for domastic purposes).In this paper,a thermal model for optimisation ... 
Masstransfer studies of solvent extraction of coals in Nmethyl2pyrrolidone
(2000)Masstransfer plays an important role in the solvent extraction of coals. The studies on the kinetics of diffusion of the solvent in coals help in understanding the process of masstransfer in coal. The coal molecules get ... 
Mathematical modeling for greenhouse heating by using thermal curtain and geothermal energy
(2004)A thermal model has been developed for the heating of a greenhouse by using inner thermal curtain and natural flow of geothermal warm water through the polyethylene tube laid on its floor. The calculations were done for a ... 
A method for digital grovernor analysis
(Elsevier Science, 1996)The use of digital devices for normal operation and control in the electric utility industry is increasing at a fast pace. By nature, the operation of these devices is discrete and so continuous system analytical techniques ... 
Modeling and comparative thermal performance of ground air collector and earth air heat exchanger for heating of greenhouse
(2005)The potential of using the stored thermal energy of ground for space heating has been investigated with the help of two buried pipe systems, i.e., ground air collector and earth air heat exchanger, integrated with the ... 
Modeling and experimental validation of a greenhouse with evaporative cooling by moving water film over external shade cloth
(2003)A mathematical model through flowing water film on shade cloth, stretched over the roofs and south wall of an even span greenhouse has been developed to study the effectiveness of cooling in greenhouse. The model was ... 
Modeling and optimal design of evaporative cooling system in controlled environment greenhouse
(2002)This communication deals with the development of a mathematical model for experimental validation of the thermal behavior in the greenhouse after evaporative cooling. Extensive experiments have been performed during July ... 
Modeling and optimal design of ground air collector for heating in controlled environment greenhouse
(2003)A mathematical model is devised to study the thermal behavior of a greenhouse while heating with a ground air collector (GAC). A computer program based on MatLab software has been used to predict the plant and room ... 
Modeling of energy distribution inside greenhouse using concept of solar fraction with and without reflecting surface on north wall
(2005)A considerable portion of the solar radiation falling on transparent north wall/roof inside an east–westoriented greenhouse is lost due to lowaltitude angle of sun during winter months. Replacing the transparent north ... 
Modified kortewegde vries solitons in an inhomogeneous plasma with negative ions
(1997)The variable coefficient modified Kortewegde Vries (mKdV) equation is derived and solved in an inhomogeneous negative ion plasma considering the plasma density and the ion drift to be spatially varying. The amplitude of ... 
Monthly performance of passive and active solar stills for different Indian climatic conditions
(2004)The monthly performance of passive and active solar stills for different Indian climatic conditions was evaluated. Numerical computations were carried out for hourly variations of average insolation at the Chennai, Jodhpur, ... 
Multiobjective load dispatch by fuzzy logic based searching weightage pattern
(2002)A multiobjective thermal power dispatch problem minimizes number of objectives viz cost and emission together while allocating the electricity demand among the committed generating units subject to physical and technological ... 
Multiobjective optimal thermal power dispatch
(1994)A multiobjective thermal power dispatch problem is formulated using noncommensurable objectives such as operating costs and minimal emission. A sensitivity measure is chosen whereby the effects of variations in the nominal ...
