Results from a high-resolution numerical simulation of the 24 May 2002 dryline convective initiation (CI) case are presented. The simulation uses a 400 km 700 km domain with a 1-km horizontal resolution grid nested inside a 3-km domain and starts from an assimilated initial condition at 1800 UTC. Routine as well as special upper-air and surface observations collected during the International H2...

An asymptotic theory is presented to describe the possible mechanism for the excitation and maintenance of torsional oscillations in rotating convective stars and planets. It is demonstrated analytically that the torsional oscillations can be excited and sustained by global thermal convection. Subject headings: convection — hydrodynamics — stars: interiors

Thermoacoustics describes energy conversion processes, activated by interaction temperature oscillation, accompanying the pressure oscillation in a sound wave, with solid boundaries. In ordinary experience this interaction of sound and heat cannot be observed, because of the very low temperature differences, but under suitable conditions, it can be emphasized and amplified to create remarkable ...

In many magnetized, dilute astrophysical plasmas, thermal conduction occurs almost exclusively parallel to magnetic field lines. In this case, the usual stability criterion for convective stability, the Schwarzschild criterion, which depends on entropy gradients, is modified. In the magnetized long mean free path regime, instability occurs for small wavenumbers when (∂P/∂z)(∂ lnT/∂z) > 0, which...

We present an overview of the relation between mantle dynamics and plate tectonics, adopting the perspective that the plates are the surface manifestation, i.e., the top thermal boundary layer, of mantle convection. We review how simple convection pertains to plate formation, regarding the aspect ratio of convection cells; the forces that drive convection; and how internal heating and temperatu...

Abnormal biological tissues possess unknown properties that must be estimated in order to decide the appropriate method of treatment terms amount dosage and place inoculation. The current work numerically investigates, for first time, simultaneous estimation several thermo-physical multi-layered from internal temperature measurements. heat propagation within is modelled by thermal-wave model bi...

Thermal management of power lithium-ion battery modules is very important to avoid thermal problems such as overheating and out control, the study behavior can provide guidance for design optimization management. In this paper, a 3d model module established based on STARCCM+ by using computational fluid dynamics (CFD) method, grid independence simulation test used determine number grids, temper...

Abstract In the traditional PMV model, calculation of human skin temperature is only related to level activity. fact, many factors such as evaporative heat dissipation, radiation and convective transfer skin. Therefore, it necessary introduce thermal physiological model modify in model. addition, considering impact activities on metabolic rate, formula calculating rate obtained from Pandolf was...
