This paper compares a 3-dimensional hydro-ecological model with a 2-dimensional model simulating the distribution and fate of Escherichia Coli (E.Coli) discharges from a sewage treatment plant discharging into Dublin Bay, Ireland. Before being discharged, the effluent from the sewage treatment plant is mixed with cooling water from a thermal generation plant resulting in a warm buoyant sewage plume that can be 7 − 9oC higher than the ambient water in the Bay. The mixing of the stratified plume is complicated by the tidal currents which transport the plume into and out of the estuary. These processes have a direct impact …


Comparative Field Performance Study Of Flat Plate And Heat Pipe Evacuated Tube Collectors (Etcs) For Domestic Water Heating Systems In A Temperate Climate, Lacour Ayompe, Aidan Duffy, Sarah Mccormack, Michael Conlon, Mick Mckeever May 2011

This paper presents a year round energy performance monitoring results of two solar water heaters with 4 m2 flat plate and 3 m2 heat pipe evacuated tube collectors (ETCs) operating under the same weather conditions in Dublin, Ireland. The energy performance of the two systems was compared on daily, monthly and yearly basis. Results obtained showed that for an annual total in-plane solar insolation of 1,087 kWh/m2, a total of 1,984 kWh and 2,056 kWh of heat energy were collected by the 4 m2 FPC and 3 m2 ETC systems respectively. Over the year, …
