A meso-channel parallel flow heat exchanger could be used as a radiator for fuel cell vehicles to dissipate waste heat from a fuel cell stack (FCS) to cooling air. Working fluid in tube-side channels was 50% glycol–water mixture. An experiment was conducted on an FCS radiator PFHX A with 2.685 mm hydraulic diameter meso-channels. The influences of condition parameters were analyzed. The critica...

According to the complexity of automobile logistics, we take one company’s automobile logistics as sample to analyze dynamics characteristics of logistic system and to set up system model by applying nonlinear dynamics theory and measure. Also, we can prove that it is applicable to study automobile logistics by this model according to the analysis of the model’s chaotic dynamics characteristics...

The present work is focused on the Graphene-based nanofluids with high thermal conductivity which helps to improve performance and enhance heat transfer. systems emphasis fluid coolant selection statistical model. Graphene a super-material, lighter than air, conductivity, chemical stability. purpose of research up Nanofluids i.e., (G) oxide (GO). Nanoparticles are dispersed in base 60:40 ratio ...

With the development of automobile industry, automobile glass type and quantity increased quickly. Automobile glass not only protects the passenger, but also affects the security, appearance of automobile and passenger’s comfort. As a result, optical performance of automobile glass, which is the most parameter, has provoked the attention of manufacturer and consumer. At present, the detection t...

Today, planning and control of logistic processes on automobile terminals are generally executed by centralised logistics systems, which cannot cope with high requirements for flexible order processing due to increasing dynamics and complexity. The main business processes on automobile terminals – notification of vehicles by automobile manufacturer, transport to automobile terminal, storage and...

A convenient mathematical formulation is given for the absolute lowfrequency response of an electrodynamic direct radiator loudspeaker mounted in a vented or unvented enclosure. The combined effects of speaker Q (ratio of reactance to resistance), enclosure size, and enclosure tuning are shown to control the convergence of the response curve towards ts asymptotic value. Mathematical criteria ar...

Noise generators are used to measure noise figure in receivers, to test system health in built-in test (BIT) circuits, in jamming, and in testing digital data transmission systems bit error rate (BER). Combining a noise generator with an antenna creates a noise radiator [1]. Such a noise radiator generates a random (non-coherent) noise field in which near-field interference is not observed. A n...
