Powiększenie wymiany ciepla można uzyskac modyfikując geometrię, co jest najbardziej efektywną techniką. Dostarczenie geometrii z pewnymi przerywanymi promotorami zakl ceń wzdluż kierunku przeplywu prowadzi do zwiększenia szybkości wymiany ciepla. W dotychczasowych badaniach rozważano lącznie pięc r żnych geometrii z r żnymi ksztaltami żeber / rowk w ulożonych wewnątrz rury. R żne geometrie brane pod uwagę to plaski prostokąt, kwadratowy rowek, prostokątny rowek, L - rowek 1 i L - rowek 2 i analizowane dla r żnych prędkości wlotowych za pomocą oprogramowania ANSYS-FLUENT. Celem pracy jest uzyskanie maksymalnej możliwej wymiany ciepla. Spośr d pięciu r żnych rozważanych geometrii, Model - 4 wykazuje maksymalne przenoszenie ciepla przez serce przy r żnych prędkościach wlotowych. Wzrost wartości wymiany ciepla jest spowodowany akumulacją przeplywu na ulożonych pletwach. Dane generowane przez oprogramowanie zachowują dobrą korelację z danymi regresji. Proponowana geometria, kt ra zostala uznana za najlepszą, może byc stosowana w r żnych dziedzinach podczas transportu plyn w lub innego preferowanego medium.

O aumento da troca t rmica pode ser adquirido modificando as geometrias, o que a t cnica mais eficaz. Ao fornecer a geometria com alguns promotores de ang stia intermitentes ao longo da dire o do fluxo levar a um aumento na taxa de troca de calor. No estudo existente existem cinco diferentes geometrias consideradas no total, com diferentes formas de aletas / ranhuras dispostas no interior do tubo. As diferentes geometrias consideradas s o nomeadamente rect ngulo plano, ranhura quadrada, ranhura rectangular, L - ranhura 1 e L - ranhura 2 e analisadas para v rias velocidades de entrada utilizando o software ANSYS-FLUENT. A inten o do trabalho obter a m xima quantidade poss vel de transfer ncia de calor. Entre as cinco diferentes geometrias consideradas, o Modelo - 4 apresenta a m xima transfer ncia de calor em v rias velocidades de entrada. Este aumento nos valores de troca de calor devido ao ac mulo do fluxo nas aletas dispostas. Os dados gerados pelo software t m mantido uma boa correla o com os dados de regress o. A geometria proposta, que se verificou ser a melhor, pode ser aplicada em v rios campos durante o transporte de fluidos ou qualquer outro meio prefer vel.

Planning strategies for Urban Green Spaces

Planning strategies for Urban Green Spaces

The world today is becoming a global village with rapid globalization and integration of markets making cities emerge as an engine of growth. There is global rise in population in cities. The cities in Asia are projected to account for large portions of global urban cover and thus risking urban green spaces. Cities of developing countries are witnessing shortage of urban green spaces as most pressing problem and India is no exception to it. There is a wide range of literature available on Urban Green Spaces but a systematic literature focusing on decision making process for greening the city is missing. Urban Green Spaces being a matter of utter importance for environmental sustainability requires immediate attention. Thus, this book investigates parameters that determine the provision of Urban Green Spaces in a city as well their associated benefits, planning issues, existing governing standards and regulations as well as various urban green space models in cities.

With the rapid growth of urbanisation, cities have been recognised to be significant global energy consumers highly dependent on fossil fuels. A considerable amount of non-renewable resources are being utilised for electricity generation and residential sector in urban area has become a major electricity consumer. Studies have revealed that the urban form places a significant impact on energy demand of buildings. In this study, by model simulation method, impact of urban form and building orientation on electricity demand for cooling and lighting has been calculated and planning interventions formulated for energy efficient residential sector in Jaipur city. Energy Simulation has been carried out on basic urban forms (detached, semi-detached and row housing) in cardinal directions with similar parameter for climatic & topographical conditions, income group, residential unit design and multi-storied building blocks. Simulation results stipulate that with change in urban form in same orientation, maximum 7% saving can be achieved in annual energy consumption for cooling.

An Assessment of Residential Area Compaction in Jaipur City

An Assessment of Residential Area Compaction in Jaipur City

The compact city is an integrated form of city with high density, mixed uses and intensification of land uses with centralised activities and higher densities. It requires provision of facilities within a walkable distance and an efficient public transport system to reduce the energy consumption and the pollution so created. The cities are expanding in size with their urban boundaries extending outwards. There is a lot of pressure on urban land which due to haphazard development is getting wasted. Compact city is a way to reduce the pressure on land by utilising it to the maximum with higher economic productivity and better environmental quality. This book discusses the various parameters which are used to measure the compactness of a city and its residential areas. Using them, the urban compact form of Jaipur city has been analysed. A comparative assessment has been done on four different residential areas in Jaipur to understand which areas are better compacted. The study is useful in making future planning policies and strategies to maintain the compact character of the city or to make it more compact for the times to come.
