Hybrid nanofluids developed with the fusion or suspension of two more different nanoparticles in a mixture as novel heat transfer fluid are currently interest to researchers due their proven better measured thermal conductivities. Several reviewed articles exist on conductivity hybrid nanofluids, vital property for which rate is directly dependent. This review aims understand current developmen...
The paper studies the effect of clay soil blocking the heat transfer area of the radiator on the engine coolant temperature by developing a mathematical model. The results of the study indicated that the percentage area covered resulted in a proportional increase of the inlet and outlet temperatures of the coolant in the radiator. The mathematically model developed also predicted the experiment...
Over the past few years, NASA has funded the development of several prototype radiator designs which use shape memory alloys to actuate cylindrical panels in response to changes in temperature. By adjusting each panel’s view to space, variable geometry radiators aim to improve the variable heat rejection capabilities of future manned vehicles in a consumable free manner. A system level radiator...
Thermostatic radiator valves (TRV) have proved their significant contribution in energy savings for several years. However, at low heat demand conditions, an unstable oscillatory behavior is usually observed and well known for these devices. This closed-loop instability is due to the nonlinear dynamics of the radiator which result in a large time constant and a large gain for the radiator at sm...
The purpose of this study was to use computational fluid dynamics software Fluent, the numerical simulation to discuss the impact pressure within the flow channel device for flat radiator fan heat flow characteristics. Piezoelectric fan was placed in front of the flow channel, and the cold air flow was introduced to the radiator cooling fan, and thus generated vortex fluid in the flow path arou...
Power series expansions in ka are derived for the pressure at the edge of a radiator, the reaction force on the radiator, and the total radiated power arising from a harmonically excited, resilient, flat, circular radiator of radius a in an infinite baffle. The velocity profiles on the radiator are either Stenzel functions (1− (σ/a)) with σ the radial coordinate on the radiator, or linear combi...
The key parameters of Cerenkov Correlated Timing (CCT) detectors are discussed. Measurements of radiator geometry, optical properties of radiator and coupling materials, and photon detector timing performance are presented.
Radiator repair workers in Washington State have the greatest number of very elevated (> or =60 microg/dL) blood lead levels of any other worker population. The goals of this study were to determine the number of radiator repair workers potentially exposed to lead; estimate the extent of blood lead data underreporting to the Occupational Lead Exposure Registry; describe current safety and healt...
