Porous media combustion (PMC) is an active field of research with a number potential advantages over free-flame combustors. A key contributor to these phenomena the interphase heat exchange and recirculation from products upstream reactants. In this paper, we present network model that captures conjugate transfer in pore-resolved 2D simulations PMC. series are presented varying solid conduction...

Simulations of bifurcated three-dimensional laminar forced convection in horizontal duct with plane symmetric sudden expansion are presented to illustrate the effects of flow bifurcations on temperature and heat transfer distributions. The stable bifurcated flow that develops in this symmetric geometry leads to non-symmetric temperature and heat transfer distributions in the transverse directio...

We investigated the effects of intravenous application of nimodipine on the neurophysiologic, biochemical, and morphologic consequences of 15 minutes of global cerebral ischemia in seven rabbits. In vivo dialysis of the hippocampus was used to determine changes in extracellular concentrations of extracellular calcium and amino acids and blood-brain barrier permeability. Ischemia without treatme...

A fuzzy linguistic model was developed to simulate the effect of leachate recirculation and sludge addition on the biogas generation in anaerobic bioreactor landfills. The model was designed using a fuzzy logic system which incorporated 3 input variables (time, leachate recirculation, and sludge addition) and a single manipulated output (biogas generation rate). The experimental work involved t...

Vascular accesses consist of permanent arteriovenous (AV) accesses (autogenous fistulas and synthetic grafts) and venous accesses (central venous catheters [CVCs]). AV accesses have fewer complications than venous accesses, and are therefore the preferred hemodialysis access. An important additional issue is whether the type of access influences adequacy of dialysis (i.e. Kt/V). Key limiting fa...

Dear Sir, Despite its limitations [1], the three-sample method is still widely used for blood recirculation estimation to detect underdialysi...

Heat transfer operations in microchannel are of special relevance designing micro-devices involving accumulation high heat flux. The current study explores simultaneously developing, unsteady laminar flow inside a twisted sinusoidal wavy and involved. A square cross-sectioned channel is taken for the study. nature as well about axis. modified geometry helps enhancing out plane mixing fluid form...

Three-dimensional numerical analyses of flow and transport characteristics in two representative multichamber ozone contactor models with different chamber width were conducted using large eddy simulation LES . Both time-averaged and instantaneous flow patterns suggest that the flow is characterized by the occurrence of large turbulent structures leading to extensive short-circuiting between ch...
