Heat Transfer and Fan Power Performance of a Developing Grooved Passage Flow Including Inlet and Exit Effects

Enhanced heat transfer surfaces are used frequently in a variety of practical devices. In the past, transverse surface grooves have shown promise in heat transfer augmentation. These lead to the formation of free shear layers and traveling waves, which augment convective transport normal to the passage walls. In the current work, two-dimensional Navier-Stokes simulations of heat and momentum transport using the spectral element technique are used to investigate the heat transfer and fan power performance of the developing regions of finite-length, grooved channel passage arrays. This study also considers the accelerating and decelerating flows entering and exiting the arrays. The computational domain has in inlet region followed by two passages stacked one above the other with thirty contiguous transverse grooves cut symmetrically into opposite walls and then a sufficiently long exit region that allows pressure recovery to take place. The performance metrics defined in the work include the average array Nusselt number and the total required fan power. The performance of the grooved channel arrays is compared with that of flat passage arrays with the same average wall center-to-center spacing (equal flow volume) for the Reynolds number range 1000 to 3000. The addition of grooves improves the overall heat transfer by a factor of 1.46 at Re=1000 and by a factor of 2.75 at Re=3000. The current calculations will provide guidance for future three-dimensional calculations of heat transfer versus fan power performance of developing flow within grooved passage arrays. Earlier studies show that three-dimensional results more accurately reproduce experimental results for Reynolds numbers greater than roughly 600

Structure of YraM, a protein essential for growth of Haemophilus influenzae

Nontypeable Haemophilus influenzae is an obligate human parasite that often causes middle ear infections in children and exacerbates chronic obstructive pulmonary disorder, the fourth leading cause of death in the United States. There are no effective vaccines available for this strain. The lipoprotein YraM (gene HI1655) was identified as essential for the growth and viability of H. influenzae but its function is unknown. Sequence comparisons showed that YraM is a fusion of two protein modules. We grew crystals of the carboxyl-terminal module of YraM comprising residues 257–573 (YraM-C), phased the diffraction data by the multiwavelength anomalous diffraction technique, and refined the model to a crystallographic R -factor of 0.16 ( R free = 0.19) with data to 1.35 Å resolution. The two-domain structure of YraM-C adopts a fold similar to that observed for the open, unliganded forms of several periplasmic binding proteins (PBPs) involved in bacterial active transport. Sequence alignments of YraM homologues from other Gram-negative species showed that the most conserved residues of YraM-C cluster between the two domains in the location where other PBPs bind their cognate ligand. Modeling of YraM-C into a closed conformation similar to the leucine-bound form of the Leu/Ile/Val-binding protein (LIVBP) shows a putative binding pocket larger than the leucine-binding site in LIVBP. The pocket has both polar and nonpolar surfaces, with the latter located in the same area where a leucine side chain binds to LIVBP. We discuss possible biological functions of YraM considering its predicted location in the outer membrane, a novel place for such a binding protein.
