1. Numerical investigation of tonal noise sources from centrifugal fan
Abstract : Heating, ventilating, and air conditioning systems (HVAC) are today an important part of many people's life. They provide a sufficient amount of airflow with the correct temperature, quality, and humidity. The negative side is the noise it produces. Many improvements have been made in building development to reduce noise from the environment. READ MORE

2. Investigation of Tonal Noise Sources from Centrifugal Fan using Detached Eddy Simulation
Abstract : Since we spend the majority of our time indoors, heating, ventilation, and air conditioning (HVAC) systems have become a more and more important part of many people´s life. They provide a sufficient amount of airflow with the correct temperature, quality, and humidity. READ MORE

3. Dry Classification of Fine Aggregates for Concrete and Asphalt
Abstract : Aggregate is defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregate for concrete production in Sweden. READ MORE

5. Ventilation Flow Field Characteristics of a Hydro-Generator Model- An experimental and Numerical Study
Abstract : Hydro-generators are complex machines used to convert the mechanical energy of the water turbine into electrical energy. Electromagnetic and mechanical losses accompany this energy conversion process which will cause heat generation and temperature increase. Cooling systems are needed to remove this excess heat from hydro-generators. READ MORE
