We show, using high-resolution three-dimensional numerical simulations, that the required transport of magnetic field from the convection zone to the overshoot region can be achieved on a convective rather than diffusive timescale by a pumping mechanism in turbulent penetrative compressible convection.

A new edition of the bestseller on convection heat transfer A revised edition of the industry classic, Convection Heat Transfer, Fourth Edition, chronicles how the field of heat transfer has grown and prospered over the last two decades. This new edition is more accessible, while not sacrificing its thorough treatment of the most up-to-date information on current research and applications in. A CIP record for this book is available from the British Library ISBN: Printed and bound in Great Britain by CPI Antony Rowe, Chippenham and Eastbourne.

A numerical study of a turbulent penetrative and recirculating flow induced by the energy input from a fire at the bottom boundary in a partially open rectangular enclosure is carried out. The compartment is connected through an opening to a long corridor, which opens into a stably stratified by: Chapter 7: Convection Gravitational Instability / Rayleigh-B´enard Convection / Top-to-Bottom Turbulent Convection / Penetrative Convection / Convection in a Rotating Fluid / Convection Modeling / Problems / Chapter 8: Turbulence Homogeneous and Isotropic Turbulence / File Size: 65KB.

Penetrative convection occurs when vertical buoyancy-driven motion originating in an unstably stratified layer of fluid penetrates into surrounding stably stratified layers.

If the Reynolds number of the flow field is sufficiently large, the fluid motion will be by: Penetrative convection does not feature a turbulent core where vn > 0 (i.e. inward moving enstrophy isosurfaces) that has been previously identified in other entraining flows such as jets or.

A plausible scenario for solar dynamo action is that the large-scale organized toroidal magnetic field is generated by the action of strong radial shear at the base of the solar convection zone, whereas the weaker poloidal field is regenerated by cyclonic convection throughout the convection zone.

We show, using high-resolution three-dimensional numerical simulations, that the required.

We study the effects of rotation on penetrative behaviour of turbulent compressible convection in a stellar-type con-vection zone. The Naviér-Stokes equations are numeri-cally solved and rotational effects are incorporated using Fig. 1 f-plane conﬁguration in which the angular velocity vector points toward the north pole.

Turbulent penetrative convection is quite distinct from its laminar counterpart and from the equivalent motions in a domain confined by impenetrable horizontal boundaries. Although overshooting would not be so deep in the solar case, the lack of true penetration extending the adiabatic region may explain why helioseismic inferences show little.

The penetrative turbulent convection is induced by the constant heat flux H 0 from the surface of a plate with diameter D ().It simulates a prototype of an urban heat island with the low-aspect-ratio plume (z i /D ≪ 1) under near-calm conditions and stably stratified atmosphere: (∂T/∂z) a = γ z > 0, where T is temperature and z is flow is assumed to be by:   Penetrative turbulent Rayleigh-B\'enard convection which depends on the density maximum of water near $4^\circ\rm{C}$ is studied using two.

The chapters in this book address the two groups of topics summarized as "Stellar Rotation and Associated Seismology" as well as "Stellar Convection and Associated Seismology".

The book offers the reader solid theoretical background knowledge and adapted seismic diagnostic techniques. Turbulence in thermal convection is investigated for flows in which the production of turbulence energy is due solely to buoyancy, and the statistics of the flow are homogeneous in horizontal planes.
