The effect of differentiating the thermal conductivity between inner and outer walls on stability a U-bend catalytic heat-recirculating micro-combustor was investigated. To this end, two-dimensional computational fluid dynamics (CFD) model developed using commercial code ANSYS Fluent (release 2020 R1) and, for different combinations values conductivities, simulations lean pre-mixed propane/air ...

  Background :Inversion recovery (IR) pulse sequences can generate T1-weighted images with a different range of inversion time (TI) to suppress or null the signal intensity (SI) for a specified tissue. In this study, we aimed to investigate the effect of TI values on the concentration of the contrast agent, which leads to a minimum signal intensity, using an inversion recovery T1-weighted 3-dim...

The generalized effective-medium theory of induced polarization (GEMTIP) is a newly developed relaxation model that incorporates the petro-physical and structural characteristics of polarizable rocks in the grain/porous scale to model their complex resistivity/conductivity spectra. The inversion of the GEMTIP relaxation model parameter from spectral-induced polarization data is a challenging is...

Tomographic imaging based on long-term ambient seismic noise measurements, mainly the phase information from surface waves, has been shown to be a powerful tool for geothermal reservoir and monitoring. In this study, we utilize data dense nodal array (192 3C nodes within 20 ) over ultra-short observation period (4.7 days) reconstruct waves determine high-resolution (0.2 km) three-dimensional (3...
