The temperature dependence of the overall heat-loss coefficient for flat-plate collectors has been studied by using stagnation measurements made with different configurations, viz., tilt 45 °s with single and double glazing and tilt 0 ° with single glazing. Comparisons have been made with...

The calculation of solar radiation received at a particular place and at a particular time, involves many factors like rotation and revolution of the earth, atmospheric attenuations, atmospheric conditions, time of day and year, geographic location of place, and site location of collector, tilt...

This paper deals with efforts to improve the performance of conventional, duct- type air heaters by providing rectangular fins in the air passage between the absorber and the rear plate. For this configuration, a mathematical model is developed by writing the energy balance equations at various...

Hazards associated with tropical cyclones are long-duration rotatory high-velocity winds, very heavy rain and storm tide. India has a coastline of about 7,516 km of which 5,400 km is along the mainland. The entire coast is affected by cyclones with varying frequency and intensity. The India...

India Meteorological Department (IMD) introduced the objective tropical cyclone (TC) intensity forecast valid for next 24 h over the north Indian Ocean (NIO) in 2003 and extended up to 72 h in 2009. In this study, an attempt is made to evaluate the TC intensity forecast issued by IMD during...

India Meteorological Department has the responsibility of monitoring and prediction of cyclonic disturbances (CDs) including tropical cyclone (TC) and depression, collection, processing and archival of all data pertaining to CDs and preparation of best track data over the North Indian Ocean...

Buildings in most countries around the world require large amounts of energy both for cooling and heating. In fact cooling loads due to solar gains represent about half of global cooling loads for residential as well as non-residential buildings. While solar gains through windows contribute...
