WebThe interaction of Rayleigh-B\'enard convection and Electro-vortex flow characterised in this work is indicative of the flow that will be found in the anodes of all discharging LMBs. WebApr 11, 2024 · Here we investigate experimentally the complete freezing process of water with dissolved salt in a standard natural convection system, i.e. the prototypical Rayleigh–Bénard cell. Due to the presence of a mushy phase, the studied system is considerably more complex than the freezing of fresh water in the same conditions (Wang …

WebApr 13, 2024 · Effect of different boundaries on the gravity-modulated Rayleigh–Bénard convection has been investigated with an emphasis on rigid–free boundaries. Small-amplitude and large-amplitude modulations are studied using the linear stability analysis. The modified Venezian approach is used to study small-amplitude modulations using … Webconsider Rayleigh-B´enard convection in a closed cylinder with radius Rand height Hthat is under uniform rotation (with an-gular velocity Ω) about the vertical axis and has a temperature difference ∆T imposed between the top an bottom surfaces.

WebFeb 20, 2003 · Local convective heat flux in turbulent thermal convection is obtained from simultaneous velocity and temperature measurements in an aspect-ratio-one convection cell filled with water. It is found that fluctuations of the vertical heat flux are highly intermittent and are determined primarily by the thermal plumes in the system. The experiment reveals … WebMar 1, 1997 · Rayleigh-B\'enard convection is numerically simulated in two and three dimensions using a recently developed two-component lattice Boltzmann equation (LBE) method. The density field of the second component, which evolves according to the advection-diffusion equation of a passive scalar, is used to simulate the temperature field. … WebDec 29, 2024 · Efficient thermal transport using passive means is highly desirable for many technological applications. A numerical study of Rayleigh-B\\'enard convection with a single passive conductive barrier over a broad range of barrier geometric parameters is presented, aiming to control the thermal transport and flow organization. It is found that, although … desks on wheels furniture
