The movement of heat in a convecting system is typically described by the nondimensional Nusselt number, which involves an average over both space and time. In direct numerical simulations of turbulent flows, there is considerable variation in the contributions to the Nusselt number, both because of local spatial variations due to plumes and becaus...

Spider pulsars are binary systems containing an energetic millisecond pulsar that intensely irradiates a closely orbiting low-mass companion. Modelling their companion's optical light curves is essential to the study of the orbital properties of the binary, including the determination of the pulsar mass, characterising the pulsar wind and the star ...

Nevihte so zaradi svoje nepredvidljivosti za letalstvo izredno nevaren vremenski pojav, saj jih pogosto spremlja močan veter, turbulenca, zaledenitve, lahko tudi razelektritve. Za pilote je torej zelo pomemben podatek o prisotnosti močno vertikalno razvitih konvektivnih oblakov v okolici in na letališčih, ki je zapisan v meteoroloških poročilih. Ke...

Glucose is an important energy source in our bodies, and its consumption results in gradients over length scales ranging from the subcellular to entire organs. Concentration gradients can drive material transport through both diffusioosmosis and convection. Convection arises because concentration gradients are mass density gradients. Diffusioosmosi...

Predictions of solar cycle 24 obtained from advection-dominated and diffusion-dominated kinematic dynamo models are different if the Babcock-Leighton mechanism is the only source of the poloidal field. Yeates et al. (2008) argue that the discrepancy arises due to different memories of the solar dynamo for advection- and diffusion-dominated solar co...

The detectability of exoplanets and the determination of their projected mass in radial velocity are affected by stellar magnetic activity and photospheric dynamics. The effect of granulation, and even more so of supergranulation, has been shown to be significant in the solar case. Our study is aimed at quantifying the impact of these flows for oth...

Au cours de ces travaux, les propriétés thermophysiques du toron de viscose ainsi que leurs évolutions pendant la carbonisation ont été étudiées. Des analyses thermiques ATG et DSC ont ainsi permis d’identifier la capacité thermique apparente du toron et les sources de chaleur liées aux transformations du précurseur. Le rapprochement de l’analyse A...

The Radiative-Convective Equilibrium Model Intercomparison Project (RCEMIP) is an intercomparison of multiple types of numerical models configured in radiative-convective equilibrium (RCE). RCE is an idealization of the tropical atmosphere that has long been used to study basic questions in climate science. Here, we employ RCE to investigate the ro...
