Abstract: The paper presents performance comparison of harmonic filters for the reduction of harmonic distortion in an industrial power system, i.e., National Tobacco Enterprise, an industry found in Ethiopia. The performance ...

The energy and cost saving of flat plate collector using Al2O3/water nanofluids and with wire coil with core rod inserts were studied experimentally. The experiments were conducted for various particle loadings of ...

The unique thing about this research work is that it is the first study out of all its kinds in Ethiopia. Ethiopia is an agricultural country and faces dearth of water resources availability for crops as well as rural ...

Abstract- Dynamic voltage restorer is considered to be one of the best device to compensate voltage sag and swell. Recently the DVRs based on direct converters are very popular and works are getting published for various ...

The aim of this paper is to achieve maximum voltage sag compensation of 52% using direct converter based DVR. The DVR topology has only two switches. The DVR is designed to compensate the voltage sag in a phase by taking ...

The synthesis method of in-situ/chemical co-precipitation was implemented for the addition of Fe3O4 nanoparticles on the surface of nanodiamond (ND) nanoparticles, and it is characterized by using x-ray diffraction, transmission ...

An experimental analysis is made to measure the heat transfer, friction factor, thermal performance, and effectiveness of Cu/water nanofluids flow in a double-pipe U-bend heat exchanger. The metallic Cu nanoparticles are ...
