In this paper, the absorbent carryover effect in a designed counter-flow enthalpy exchanger is investigated. In a built prototype of the liquid desiccant dehumidifier, air and the absorbent solution are in contact and flow through a packed multi-channel polymer tower in a counter-flow pattern. To avoid the absorbent carryover, the tower is equipped with an eliminator. Experimental measurements ...

Numerical simulations for flow past a finite rectangular wing with NACA 0012 section at $Re=1000$ various semi-aspect ratios ( $0.25\le sAR \le 7.5$ ) over range of angles attack $0^{\circ }\le \alpha 14^{\circ }$ reveal streamwise vortices, which increase in strength and number to occupy an increasing spanwise extent $\alpha$ . They result non-monotonic variation local force coefficients incre...

In this paper, a low-power structure called bypass zero, feed A directly (BZ-FAD) for shift-and-add multipliers is proposed and implemented. The architecture considerably lowers the switching activity of conventional multipliers. The modifications to the multiplier which multiplies by include the removal of the shifting the register, direct feeding of to the adder, bypassing the adder whenever ...

dye-sensitized solar cells present promising low-cost alternatives to the conventional silicon (si)-based solar cells. the counter electrode  generally consists of pt deposited onto fto plate. since pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. carbon nanotubes  have shown significant properties such...
