Optimal Design of a Muffler with Perforated Plates Considering Pressure Drop

Study of pressure drop for perforated plates and TAD-fabrics

The aim of this paper was to study the relationship between pressure drop and superficial velocity for fabrics used in Through Air Drying and also for perforated plates. Experiments were performed to measure this relationship and the experimental data was then compared to different theoretical models. It was hard to get good agreement between the models and the experimental data for the perfora...

Optimal Muffler Design

Optimal Design of a Microgrid with Multiple Energies Considering Reliability

The unprecedented penetration of distributed generation in distribution network provides utilities with a unique opportunity to manage portions of networks as microgrids (MG). The implementation of an MG may offer many benefits, such as capital investments deferral, reduction of greenhouse gas emissions, improvement in reliability, and reduction in network losses. In order to draw the most effe...

Perforated Muffler Manifold Catalyst

An alternative exhaust manifold system, the Perforated Manifold, Muffler, and Catalyst (PMMC), is proposed to improve sound suppression while reducing engine pumping losses and exhaust emissions. One-dimensional predictions from acoustic theory are used to configure the initial design. Preliminary evaluation of the concept is based on bench tests, including an extended impedance tube set-up for...

Exergy , economy and pressure drop analyses for optimal design of recuperator used in microturbine

The optimal design of a plate-fin recuperator of a 200-kW microturbine was studied in this paper. The exergy efficiency, pressure drop and total cost were selected as the three important objective functions of the recuperator. Genetic Algorithm (GA) and Non-dominated Sorting Genetic Algorithm (NSGA-II) were respectively employed for single-objective and multi-objective optimizations. By opt...
