The affected pig should be restrained and the corrugated tube gently inserted into the lumen of the prolapsed rectum the halfway-point on the tube needs to be inserted as far as the anal sphincter. The rubber bands should be stretched over the prolapse and placed as near as possible to the perianal skin; they must be tight enough to stop the blood supply to the prolapse. Faeces may move down th...

Turbulent heat transfer in Helically Corrugated Tubes (HCT) was numerically investigated for pure water and SiO2 nanofluid using Computational Fluid Dynamics (CFD). This study was carried out for different corrugating pitches (5, 7, 8 mm) and heights (0.5, 0.75, 1.25 mm) at various Reynolds numbers ranging from 5000 to 13300. The effect of nanoparticles on heat transfer augmentation for plain t...

this paper presents a three-dimensional numerical investigation carried out in turbulent forced convection in a tube with helical ribs. enhancement of heat transfer using helically corrugated tubes has beenstudied experimentally by many researchers but there exist a few published numerical analyses results. the paper also introduces the results of heat transfer and friction factor data for inco...

In present work, comparison of three different tube bundles for particular heat exchanger is proposed. Three types are smooth, micro finned and corrugated tubes. Heat exchanger will be designed with smooth tube bundle and simulated. Micro fin and corrugation over tube is applied separately for same heat exchanger in feasible size and simulated for performance. Besides, comparison is done with h...

dotracheal tube and are composed of inspiratory and expiratory corrugated limbs. The two breathing tubes carry respiratory gases with volatile anesthetics to and from patients during general anesthesia. Although longer corrugated breathing tubes allow the anesthesia machine to be located farther from the patients, they are so long and flexible that they tend to hang down below the operating tab...

To maximize the controllable energy absorption of corrugation troughs as observed in the single sided corrugated (SSC) tube, we proposed and tested a new structure design, i.e., double-sided corrugated (DSC) tube made of Al 6060-T6 aluminum alloy or CF1263 carbon/epoxy composite. Finite element models were developed to test the mechanical advantage of the DSC tube in comparison with both SSC an...
