Short Courses

Brief Summary: In these days green and clean processing techniques receive greater attention in a wide variety of technologies. In this connection, this short course offers an excellent opportunity and intends to expose the participants to learn about the fundamentals, effective usage and technological applications of ultrasound. With proper learning and understanding, ultrasound could be employed in an energy efficient way. Besides, the discussion will be made about the translation of lab scale to plant scale. The presenter has a very long experience in designing ultrasound reactors and thus it is an opportunity to learn this technique in an easy way through this short course.

Brief Summary: Most muffler design is accomplished by using “cut-and-try” methods that rely on what has worked in the past and/or extensive full-scale testing on engines for validation. This approach can be extremely costly, in particular with regard to large industrial mufflers, in terms of testing or in other losses caused by inability of the design to meeting the project criteria. New computer software aimed at muffler design can shorten the design cycle and yield more effective results.
This eight hour seminar provides an introduction to the behavior of mufflers and silencers including a description of the two-port approach to muffler design. The seminar covers the acoustic simulation of muffler and silencer systems and the use of experimental methods to measure muffler performance. Following a review of basic muffler concepts and definitions, the seminar will focus on meeting design objectives such as insertion loss with a specified back pressure requirement. It will show how modern software such as SIDLAB can be used to model both the acoustics and flow in achieving the design objective and the role that 1D engine simulations can play in providing important input. The final topic will cover optimization of muffler design to meet a specified design objective with a specified space constraint. The main focus is on large and small IC-engine intake and exhaust systems, but most of the information is also applicable to any pipe or duct system.

Learning Objectives: By attending this seminar, you will be able to:
– Explain the underlying principles of mufflers and silencers
– Gain insight into muffler and silencer design concepts using contemporary software
– Understand experimental methods for measuring muffler and silencer performance

Who Should Attend: This course is designed for engineers and technical managers seeking an understanding of the principles of muffler design and an introduction to the use of muffler and silencer design software. In addition, others that design, purchase, or manufacture muffler or silencer systems will also benefit from the information presented in this seminar.

Prerequisites: Knowledge of basic acoustics is assumed. Mathematics to an engineering degree level is desirable, but not required.
