Dynamics of fluid and heat flow in a CO2-based injection-production geothermal system
Binary system CO2-water displacement Heterogeneity Preferential flow
2018/3/23
CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
Heat and mass transfer from the mantle: heat flow and He-isotope constraints
heat flow helium isotope ratio geothermal energy mass transfer
2015/9/10
Terrestrial heat flow density, q, is inversely correlated with the age, t, of tectono-magmatic activity in the Earth's
crust (Polyak and Smirnov, 1966; etc.). «Heat flow-age dependence» ind...
This is an announcement of our work [5] on introducing and studying a geometric heat flow to find Killing vector fields on closed Riemannian manifolds with positive sectional curvature. We study its v...

Symmetry analysis and exact solutions of semilinear heat flow in multi-dimensions
Symmetry analysis exact solutions semilinear heat flow in multi-dimensions
2010/11/24
A symmetry group method is used to obtain exact solutions for a semilinear radial heat equation in $n>1$ dimensions with a general power nonlinearity. The method involves an ansatz technique to solve...

2010/7/8
In this paper we present a spatially homogeneous locally rotationally symmetric (LRS) Bianchi type -V perfect fluid model with heat conduction in scalar tensor theory proposed by Saez and Ballester. T...
Three dimensional seminumerical model to study heat flow in peripheral layers of elliptical shaped human limbs
Variational form Finite element method
2010/9/17
A number of attempts have been made to study heat flow in circular cross-section of human limbs. But almost no attempt has been reported in literature about study of heat flow in the tissue layers of ...
