POMA : a zonal model for airflow and temperature distribution analysis
A zonal model is a new kind of numerical model to simulate the airflow and temperature distribution within a room by means of personal computers. It is an intermediate model between multizone and Computational Fluid Dynamics (CFD) model. Compared to multizone models, zonal models can provide …

A zonal model for radiation heat transfer in coal-fired boiler furnaces
… exchangers downstream of the furnace. Having a model that can predict the furnace exit temperature and heat flux distributions may enable furnace performance to be predicted without having to conduct extensive experimentation. Also, comparing the results with measurements taken on the plant may …

Nursing in secure and forensic psychiatry: contexts, contributions and concepts
… of practice, are made and mapped to produce a zonal model of secure and forensic nursing. The zonal model is a way of understanding how the research submitted in support of the thesis makes a contribution to a coherent field of practice. It also facilitates a redefining of the forensic …

Implementing a time- and location-differentiated cap-and-trade program : flexible nitrogen oxide abatement from power plants in the eastern United States
… To address these questions, this work used a zonal model based on an abstract network graph and optimal power flow simulations to estimate potential short-term NOx reductions and associated costs from redispatch of power plants in the original Pennsylvania-New Jersey-Maryland (PJM) power …

Thermal room modelling adapted to the test of HVAC control systems
Room models, currently used for controller tests, assume the room air to be perfectly mixed. A new room model is developed, assuming non-homogeneous room conditions and distinguishing between different sensor positions. From measurement in real test rooms and detailed CFD simulations, a list of …

Development and application of low Reynolds number turbulence models for air-cooled electronics
… equations for momentum and turbulence. RANS models are popular as they are much quicker to solve than time-dependent models such as Large Eddy Simulation (LES) or Direct Numerical Simulation (DNS). At present the majority of thermal design engineers use the standard k-e model which is a high …
