Measurement and Control of Marine Diesel Engine Nox and Co2 Emissions

為了解決Exhaust pipe的問題，作者Hountalas, Dimitrios,Pariotis, Efthimios 這樣論述：

Prof. Dimitrios Hountalas was born in 1961 in Greece. He finished his elementary studies at Chicago Illinois USA and Greece. He received his Diploma in Mechanical Engng from the National Technical University of Athens (NTUA) in 1985 and his PhD degree in 1989. In 1991 he became Lecturer at NTUA and

was promoted to Assistant Professor in 1995. In 2001 he became Professor Associate and in 2007 Professor for Internal combustion engines. His field of specialization is Internal Combustion Engines and specifically: Diesel Engine Modelling, Diagnostics & Condition Monitoring, Diesel Engine Emission R

eduction Techniques, Diesel Engine Performance and Emission Measurement, Exhaust Heat Recovery from Diesel Engines, Dual Fuel Combustion and Alternative Fuels.Prof. Hountalas has participated in a number of projects funded by the EU and the private sector focusing on diesel engine performance and em

issions. Most of the work has been conducted with major engine manufacturers. Prof. Hountalas has developed an advanced simulation code for both diesel engine performance and emission prediction that has been used and evaluated by engine makers worldwide. Moreover he has over 25 years field experien

ce having cooperated with major companies in Greece and abroad (power generation, marine sector, engine manufacturers). During this period he has also conducted numerous on-board applications on vessels during sea trials in cooperation with major shipping companies and recognized ship yards (Hyundai

Korea, DSME Korea, SWS China). His research work has been published in over 200 publications and he has developed a prototype diagnostic technique for diesel engines which has been included as reference technology in the: ＂Diesel Engine Reference Book＂. Prof. Hountalas has developed in co-operation

with a German Based Company a Reference Technique for On-Board NOx emission verification which has received an Official GL Marpol Type Approval in 2012. In 1989 Prof. Hountalas received the ＂ASME-E.F. Obert Outstanding Paper Award＂ and in 2004 and 2010 the ＂SAE Award＂ for Presentations at the World

Congress in Detroit.Dr. Efthimios Pariotis was born in 1972 in Greece. He received his Diploma in Mechanical Engng from the National Technical University of Athens (NTUA) in 1995 and his PhD degree in 2005. From 2005 until 2009 he has been a research associate at the Internal Combustion Engines Lab

oratory (ICEL) of NTUA. From 2005 to 2008 he has been an adjunct lecturer at the Hellenic Army Academy, being responsible for teaching ＂Internal Combustion Engines＂. Since 2009 he is lecturer at the Hellenic Naval Academy, responsible for teaching the courses of ＂Heat Transfer＂, ＂Marine Auxiliary Sy

stems and Pipe Networks＂ and ＂Thermodynamics＂. His field of expertise is Internal Combustion Engines with emphasis in: Development of Diesel Engine Simulation Models for engine Performance and Emissions, Diesel Engine Emission Reduction Techniques, Exhaust Heat Recovery from diesel engines and Heat

Transfer in Internal Combustion Engines. Dr. Pariotis has participated in a number of projects funded by the European Union and the private sector in cooperation with the ICEL of NTUA, focusing on diesel engine performance and emissions. Most of these projects have been conducted in cooperation with

major international engine manufacturers. His research work has been published in 25 publications at International Journals and Conferences.

多腔體消音器之聲學性能設計與分析

為了解決Exhaust pipe的問題，作者林迺凱 這樣論述：

本研究著重於多腔體消音器之小型船消音器（Alpha）、大型船艦消音器（Bata、Gamma）聲學性能設計與分析。首先，利用相關文獻來驗證本文之傳輸矩陣法與有限元素法所計算的傳輸損失之正確性，並進行聲學性能的定性、定量分析，接著，將傳輸矩陣法用於Alpha消音器的初步變更設計，並使用有限元素法相互比較；而最佳化是利用Nelder-Mead Method，結合有限元素法迭代至最佳相對公差，並求出Beta消音器優化後的尺寸與傳輸損失。利用傳輸矩陣法進行的Alpha消音器初步變更設計時，當計算頻率接近非平面波之激發頻率，或接近Karal Factor可修正頻率之上限時，傳輸矩陣法就會失去準確度。因此

，膨脹管直徑很大的消音器，傳輸矩陣法可用頻率會受限於很低的頻率範圍。Beta消音器之優化設計，是先將腔體體積縮小至原始設計腔體體積的72.9%後，並期望在分析內的所有頻率皆呈現較為均勻的傳輸損失。以全頻段優化結果來說，Beta消音器之前、後消音器的傳輸損失在頻率140赫茲以上皆至少有10分貝效果。不過，在低頻段（50赫茲到180赫茲）與高頻段（900赫茲到2850赫茲）之傳輸損失，與頻率在180赫茲到900赫茲（中頻段）相比，仍有待提升。因此，如果僅優化低頻段與高頻段之頻率，其傳輸損失的優化結果在頻率高於90赫茲時皆優於全頻段優化設計，且在頻率高於180赫茲以上時，也皆優於Gamma消音器。最

後，低頻、高頻段之優化，驗證了中頻段的頻率較容易透過不同的優化方式，而保持相對優異的傳輸損失，因此將來進行優化設計時，僅需要針對低頻、高頻段之頻率，來進行目標函數的計算，不僅可以節省許多計算成本，也可以得到相對於全頻段優化的優異成果。
