An experiment aimed at investigating the antenna properties of different plasma structures a column as reconfigurable antenna, is reported. A 30 cm long excited by surface wave, which acts antenna. By changing operating parameters, e.g., working pressure, drive frequency, input power, radius glass tube, length column, and argon gas, single (plasma column) can be transformed to multiple small elements blobs). It also reported that number, length, separation between two controlled parameters....
An experimental study has been carried out to analyze the effect of inclined ribs used as roughness element on heat transfer along its friction characteristics. The parameters include relative pitch (P/e) ranges from 4–16, height (e/Dh) 0.021–0.043 and angle attack (α) 30° 75°. Reynolds number (Re) lies in range 4500–28000. factor data obtained experiment it is compared with smooth duct under same conditions. Considerable augmentation was observed over duct. Correlation also developed for...
The fluid flow characteristics and heat transfer in triangular duct solar air heater (SAH) have been studied experimentally numerically for Reynolds number range from 4000 to 18,000. In the present paper, three different models of were considered, namely, model 1 with simple duct, 2 rounded corner on one side triangle fixed radius curvature 0.39 times height as passage, 3 roughness absorber plate SAH. apex angle values are assumed constant all SAH, i.e., 160 mm 60 deg, respectively....
Purpose The purpose of this computational fluid dynamics (CFD)-based study on semicircular rib-roughened equilateral triangular duct is to investigate heat transfer, friction factor and thermohydraulic performance parameter. analysis carried out by simulating problem in ANSYS (Fluent). Reynolds number the varies from 4,000 24,000. Nusselt calculated for different using various turbulent models available (Fluent) a smooth compared results with Dittus–Boelter correlation....
Turbulent flow heat transfer and friction penalty in triangular cross-sectional duct is studied the present paper. The sharp corners of are modified by converting it into circular shape. Five different models were designed fabricated. Heat through all was investigated compared conventional under similar conditions. curvature radius rounded for kept constant (0.33 times height). numerical simulations also performed obtained result validated with experimental findings close match observed...
The working medium is air in a solar heater (SAH) and because of its low heat-transfer coefficient, SAH results poor performance. By placing artificial-roughness over the heat-collector plate, performance can be improved significantly. improvement thermal hydraulic by providing multiple-arc-rib roughnesses patterns with gap discussed generalized correlations are developed for Nusselt number friction factor based on collected from experimentation (under steady condition). In total seven...
A 30 cm long plasma column is excited by a surface wave, which acts as antenna. Using properties (pattern formation/striations in plasmas) single antenna can be transformed into array, helical, and spiral Experiments are carried out to study the power patterns, directivity, half beam width of such different antennas. Moreover, field copper studied. Further, wireless communication jamming capability tested. Findings this suggest that directivity range increased converting array/helical/spiral...
The sharp corner significantly affects the flow through triangular duct. In corners, gets stagnant, which results in poor heat transfer. Therefore, present study, one of duct is kept rounded with variable curvature radius values (Rc). selected such a way that it varied from minimum value (i.e., Rc = 0.33 times height; h) to maximum 0.67h,which named as conventional work). addition this, combined effect both and dimple-shaped intrusion has also been studied on air transfer for this purpose;...
The present work deals with the vibrational spectroscopic signature of synephrine molecule and its radical in gas phase. We have optimized synephrine- ground state. optimization neutral de-protonated has been performed at B3LYP/6-31++G(d, p) level theory. comparison frequencies both structures also made. Most are good agreement experimental ones. effect hydrogen removal from site oxygen atom upon geometrical parameters reported. Subsequently, different thermodynamical calculated room...
