When coupling computational fluid dynamics (CFD) with a detailed thermal comfort model describing the human thermoregulation, the characteristics of the micro-climate of the human body have to be known. In the paper, CFD has been applied to investigate human body’’s micro climate. A climate chamber equipped with a thermal manikin has been used to validate the CFD simulations against measurement...

This paper introduces computational fluid dynamics (CFD), a numerical approach widely and successfully used in aerospace engineering, to deal with surface traffic flow related problems. After a brief introduction of the physical and mathematical foundations of CFD, this paper develops CFD implementation methodology for modeling traffic problems such as queue/platoon distribution, shockwave prop...

Although gender discrimination has been illegal in organizations since the passage of the Civil Right Act of 1964, individuals remain hesitant to claim internally by making members of their employing organization aware of gender discrimination. Yet surprisingly little research has examined the individual difference and contextual antecedents to internal discrimination claims. We advance an inte...

Gastric cancer (GC) is the fourth most common cancer and the second major cause of cancer-related deaths worldwide. In our previous study, a novel and sensitive method for quantifying cell-free DNA (CFD) in human blood was established and tested for its ability to predict patients with tumor. We want to investigate CFD expression in the sera of GC patients in an attempt to explore the clinical ...

KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...

Current CFD calibration work has mainly focused on the CFD model calibration. However no known work has considered the calibration of the CFD results. In this paper, we take inspiration from the image editing problem to develop a methodology to calibrate CFD simulation results based on sparse sensor observations. We formulate the calibration of CFD results as an optimization problem. The cost f...

OBJECTIVE This study aimed to predict recurrence after coil embolization of unruptured cerebral aneurysms with computational fluid dynamics (CFD) using porous media modeling (porous media CFD). METHOD A total of 37 unruptured cerebral aneurysms treated with coiling were analyzed using follow-up angiograms, simulated CFD prior to coiling (control CFD), and porous media CFD. Coiled aneurysms we...

BACKGROUND Traumatic brain injury (TBI) is a major cause of death and disability. In this study a new method to measure cell free DNA (CFD) for the management of TBI is tested. Our hypothesis was that CFD concentrations correlate to the magnitude of brain damage, and may predict the outcome of injured patients. METHODS Twenty eight patients with isolated head injury were enrolled. Their demog...

Extensive testing with a plasma torch operating on methane in a supersonic crossflow sparked an interest in modeling the torch using CFD to determine if methane plasma jets can be accurately modeled, and if so, to ascertain the usefulness of such results. The comparison presented here is of a methane plasma jet produced by a normally oriented plasma torch in a Mach 2.4 crossflow and the corresp...

Energy simulation (ES) and computational fluid dynamics (CFD) provide important and complementary information for building energy and indoor environment designs. A coupled ES and CFD simulation can eliminate many assumptions employed in the separate ES and CFD computations and thus provide more accurate results. Through theoretical analysis and numerical experiment, this study verified that the...
