Morton-Ordered Gpu Lattice Boltzmann Cfd Simulations With Application To Blood Flow, Gerald Gallagher, Fergal J. Boyle
Morton-Ordered Gpu Lattice Boltzmann Cfd Simulations With Application To Blood Flow, Gerald Gallagher, Fergal J. Boyle
Conference Papers
Computational fluid dynamics (CFD) is routinely used for numerically predicting cardiovascular-system medical device fluid flows. Most CFD simulations ignore the suspended cellular phases of blood due to computational constraints, which negatively affects simulation accuracy. A graphics processing unit (GPU) lattice Boltzmann-immersed boundary (LB-IB) CFD software package capable of accurately modelling blood flow is in development by the authors, focusing on the behaviour of plasma and stomatocyte, discocyte and echinocyte red blood cells during flow. Optimised memory ordering and layout schemes yield significant efficiency improvements for LB GPU simulations. In this work, comparisons of row-major-ordered Structure of Arrays (SoA) and Collected …
Optimising Existing Digital Workflow For Structural Engineering Organisations Through The Partnering Of Bim And Lean Processes, John Mclaughlin, Barry Mcauley
Optimising Existing Digital Workflow For Structural Engineering Organisations Through The Partnering Of Bim And Lean Processes, John Mclaughlin, Barry Mcauley
Conference Papers
Building Information Modelling (BIM) is now seen as one of the leading transformative processes within the Architectural, Engineering and Construction (AEC) sector and has the potential to assist in streamlining the structural design process. However, its practical implementation can often add another layer to the existing workflow and can result, to its detriment, in the primary objective of optimising structural workflows being hindered. This can lead to structural organisations producing 3D models in tandem with traditional drawings, a lack of human intervention regarding software interoperability, and a reluctance to move away from conventional work methods. This paper will explore how …
Comparison Of Predicted And Measured Annual Performance Of A Roof-Top Grid-Connected Pv System In The Irish Climate, Chibuisi Chinasaokwu Okorieimoh, Brian Norton Prof, Michael Conlon Prof
Comparison Of Predicted And Measured Annual Performance Of A Roof-Top Grid-Connected Pv System In The Irish Climate, Chibuisi Chinasaokwu Okorieimoh, Brian Norton Prof, Michael Conlon Prof
Conference Papers
The problem of energy scarcity has reached a global scale as a result of the majority of energy production relying on non-renewable sources of energy. Solar photovoltaic cells use the photovoltaic effect to convert solar energy into electrical energy. Solar energy can reduce emissions of carbon dioxide (CO2) associated with the generation from fossil fuels as the only CO2 emissions are those embodied in their manufacture. A 268.8 m2 area roof-top grid-connected PV system with a total capacity of 49.92kWp was installed at Warrenpoint (54.11oN and 6.26oW) in Ireland. 192 “Renesola” …

Reviewing The External Factors That Influence Pv Output Performance In The Irish Climate, Chibuisi Chinasaokwu Okorieimoh, Brian Norton Prof, Michael Conlon Prof
Conference Papers
The literature review presented in this paper centres on the external factors that influence PV output performance in the Irish climate.
Solar photovoltaic (PV) panels show long-term performance degradation, resulting in lower like-per-like efficiencies and performance ratios. Manufacturers of solar photovoltaic modules typically guarantee a life span of more than 20 years. But to meet such guarantees, it is necessary to track and mitigate PV module degradation during this period, and identify maintenance and repair requirements beyond this period. Solar PV modules degrade over time, becoming less efficient, less reliable, and, eventually, inoperable.
External factors such as solar irradiance, dust …
Development & Validation Of A Piv System For Obtaining Data From A Uasb Reactor, Camila D' Bastiani, Gerald Gallagher, David Kennedy, Anthony Reynolds
Development & Validation Of A Piv System For Obtaining Data From A Uasb Reactor, Camila D' Bastiani, Gerald Gallagher, David Kennedy, Anthony Reynolds

Anaerobic digestion processes can generate energy in the form of biogas while treating organic wastewater. The efficiency of the treatment, and thus the generation of biogas, is closely linked to the type and design of the reactor, and the technology used. Granular anaerobic digestion technology offers advantages such as a higher loading rate and reduction of the space needed. However, the hydrodynamics inside this type of reactor can be complex due to the presence of solids (granules) and gas (biogas) phases along with the liquid phase (wastewater). This is one of the reasons why the study and optimization of reactors …

Electric Vehicles: Design, Development And Growth Directions, David Kennedy
Conference Papers
The transition from Petrol/Diesel and LPG powered vehicles to electric types and hydrogen powered is in progress. The world demand, from China to UK and Tokyo to New York is growing and includes new brands to established companies. Toyota has developed Hybrids on almost all of its Petrol/Diesel models during this transition. The scale of the industry is enormous with experts arguing for and against the performance, sustainability, ethical reasoning, costs and reliability of the technology for now and the future, providing logical answers to support or reject their arguments for success or failure. One in 12 cars sold across …
