Considering the influences of heat transfer rate in automotive radiators on several aspects such as engine performance, fuel economy and available space for components, present study numerically investigates impacts different nanofluids pressure drop an radiator. Four parameters each having four levels are taken into consideration, which nanoparticle volume fraction ( $$\phi =0.1, 0.3, 0.7$$ , ...

In this paper, a monopole UWB broadband antenna is designed, fabricated, and measured for wireless communication networks. The initial radiator model of the proposed has short-sleeve shape, to expand impedance bandwidth, right left angles are subtracted symmetrically from lower half radiator. matching improved by etching slots in feed line adding L-shaped patches on both sides line. results sho...
