The Impact of Astronomically Induced Insolation Variations on the Extent of the Martian Cryosphere
Introduction: Estimates of the global inventory of water on Mars based on a determination of the amount of water required to erode the outflow channels suggest that a quantity equivalent to a global ocean 0.5 to 1 km deep may be stored in the planet’s subsurface [1, 2]. As this inventory post dates the timing of the most efficient processes that may have lead to its removal, the majority of thi...
متن کاملEffects of heat generation and thermal radiation on steady MHD flow near a stagnation point on a linear stretching sheet in porous medium and presence of variable thermal conductivity and mass transfer
The present paper was aimed to study the effects of variable thermal conductivity and heat generation on the flow of a viscous incompressible electrically conducting fluid in the presence of a uniform transverse magnetic field, thermal radiation, porous medium, mass transfer, and variable free stream near a stagnation point on a non-conducting stretching sheet. Equations of continuity, momentum...
متن کاملModeling the thermal and physical evolution of Mount Sharp's sedimentary rocks, Gale Crater, Mars: Implications for diagenesis on the MSL Curiosity rover traverse
Gale Crater, the Mars Science Laboratory (MSL) landing site, contains a central mound, named Aeolis Mons (informally Mount Sharp) that preserves 5 km of sedimentary stratigraphy. Formation scenarios include (1) complete filling of Gale Crater followed by partial sediment removal or (2) building of a central deposit with morphology controlled by slope winds and only incomplete sedimentary fill. ...
متن کاملValidation of air freezing index (AFI), for determination of frost penetration depth in typical arid and semi-arid zones of Iran
Depth of frost penetration is one of the main indices in agriculture, civil and transportation engineering. Soil temperature is a function of several factors including: topography, solar radiation, air temperature, moisture content and other physical properties of soil such as thermal capacity, coefficient of heat conductivity, and specific heat. The main objective of the present paper is to de...
متن کاملInvestigation into the Effects of Nanoparticle Size and Channel Depth on the Thermophysical Properties of Water Nanofluids in the Nanochannel Using Molecular Dynamics Simulation
In this research, an in-house code which uses the molecular dynamics method to study the flow of different nanofluids in the copper nanochannel and computes the thermo-physicals properties has been developed. The flow of nanofluids has been studied from hydro-thermally viewpoint and temperature jump at the wall has been applied. Parametric study to consider the effect of different parametric su...
