A New Approach for Inlet Diffuser of Automotive Catalytic Converter Considering Conversion Efficiency of Pollutants
The monolithic catalytic converter is still the main pollution control device for modern vehicles in order to reach the ever-increasing legislative demands for low emission standards. The catalytic converters require a large expansion from the exhaust pipe to the front face of the monolith. Unfortunately, packaging constraints often do not permit the use of long diffusers. Hence, flow separa...
متن کاملThe role of natural ventilation on reducing indoor radon concentration
Due to the increasing of closed ventilation systems used in buildings, the risk of indoor radon is increased day by day. In this study, we selected two sample rooms to calculate the radon emission coefficient from different levels, radon concentration measured when the natural ventilation was completely closed and compared with the analytical results. The results clearly show the difference in ...

متن کاملDesign of Air Distribution System for Operation Theatre Using Flow Visualization Techniques to Improve Flow Characteristics
Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...
متن کاملIslanding Detection and Frequency Circuit Measurement by Power Distribution Relation Depending on the Angle
This paper presents a new islanding detection method based on the difference of the power transfer angle between the distributed generation and local load. After islanding, current id and iq will be changed by adding the variation to d_q transformation block of current. This makes voltage and frequency disturbance and therefore islanding is recognized. Active islanding detection method usually ...
