Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. In this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...

Modeling the human larynx can provide insights into the nature of flow within the glottis. This study reports intraglottal pressure profiles and flow visualization for a symmetric and an oblique glottis with a glottal angle of 10 deg divergence. For the oblique case, the glottis slanted at an angle of 15 deg. A Plexiglas model of the larynx was used. Each vocal fold had at least 11 pressure tap...

Unsteady simulations of stagnation point flames are conducted in order to study flame turbulence interactions in a relatively simple flow environment. Flame propagation is represented using a flamelet model called the G equation. Two subgrid models are used to close the filtered G equation. The effects of significant heat release on the turbulent flow and the effect of varying turbulence intens...

In this part of the investigation, flow-field properties of hydrogen jets injected into a hypersonic flow are reported. The combustor has a single fuel injection parallel to the main flow from the base. The numerical simulation has been done with finite rate chemistry model using K-ε turbulence model. The results obtained through the numerical simulation of the cavity based fuel injectors are p...

Current capabilities for numerical simulation of laminar shock-shock interactions are examined. Two fundamental configurations are considered: the Edney IV shock-shock interaction and the crossing oblique-shock interaction generated by a double wedge configuration. Two cases for each configuration were examined by a distinguished group of international researchers using the Reynolds-averaged Na...

Dysmenorrhea is one of the most common gynecologic complain, especially among young women. It influences daily activities, and lowers life quality. In clinical practice, non-steroidal antiinflammatory drugs (NSAIDs) are used as the firstline treatment for dysmenorrhea. However, longterm use of these medications is associated with side effects. Some Chinese herbal medicines (CHMs) were reported ...

Divalent cationic strontium (Sr2~-l adsorption to and desorption from iron corrosion products were examined in two model drinking water distribution systems (DWDS). One system was maintained with chlorine-disinfected drinking water and the other with the same water with secondary chloramine disinfection. Flow conditions simulated primary transmission lines (constant flow) and residential mains ...

The present research investigated the role of blood viscosity on flow within a microvascular network to identify the conditions of blood flow stagnation. When the yield stress of blood was less than 0.005 Pa, there were no stagnant regions in the microvasculature. However, when the yield stress increased to 0.05 Pa, stagnant or reduced flow areas began to appear, which grew and expanded rapidly...

This paper presents an experimental investigation on the primary and secondary peak heat transfer characteristics of obliquely (45°) impinging jet a flat smooth target surface. Local convective coefficients have been calculated through transient liquid crystal thermography technique employing one-dimensional semi-infinite conduction model for The effects Reynolds number (Re) jet-to-target spaci...

The classical Helmholtz problem is applied for modelling and numerical investigation of inviscid cusp-ended separated flow around circular cylinder. Two coordinate systems are used: polar for initial calculations and parabolic as topologically most suited for infinite stagnation zone. Scaling by the shape of the unknown free line renders the problem to computational domain with fixed boundaries...
