Flow mixing characteristics inside a wire-wrapped 37-pin bundle were measured using a wire-mesh sensing system. The subchannel flow mixing within a sodium-cooled fast reactor (SFR) core subassembly is an important phenomenon to predict temperature di

In this study, the electrical impedance imaging of two-phase flows undergoing rapid transient is considered with a special emphasis on the effect of the current pattern on the image reconstruction. As observed in the companion paper, the trigonometri

We present an integral approach to estimate temperature-dependent thermal conductivity and heat capacity per unit volume simultaneously in a transient non-linear heat conduction medium. It is assumed that the thermal property is a monotonic function

We introduce the electrical impedance tomography (EIT) technique for the possible application to the visualization of binary- and ternary-mixture systems. In the EIT, the internal image is reconstructed from the resistivity (or conductivity) distribu

We present a non-iterative direct method to estimate time-varying boundary heat flux in a one-dimensional heat conduction domain with heated and insulated walls. The proposed method relates the temporal variation of the surface heat flux to the tempe
