The study of spray impact on the heated sapphire plate

The process of the liquid spray impact on the heated surface is studied experimentally using the IR-transparent sapphire plate method. The spatiotemporal distribution of the temperature field on the sapphire substrate surface during impacting spray is received. The obtained experimental data are an important step in a study of the local characteristics of heat transfer in the areas of the contact lines during liquid spray impact on the heated surface. Further, the local heat fluxes and heat transfer coefficients will be determined by solving the problem of thermal conductivity in the sapphire substrate.

Spatiotemporal distribution of the temperature field inside the thin heated foil during impacting liquid spray

The spatiotemporal distribution of the temperature inside a constantan foil during impacting spray is resolved experimentally in the present work. The received infrared image sequence will be used to find the local and average heat transfer coefficient of the foil. In the future, the results obtained will be used to calculate the heat flux in the region of the contact line of each drop.

Application of Modified Gastric Tube Placement in Patients with Indwelling Gastric Tube

Objective: To explore the effect of modified nasogastric tube placement and Rehabilitation New Liquid Spray in patients with indwelling gastric tube. Methods: Eighty-six cases with indwelling gastric tube in our hospital from January 2020 to May 2021 were randomly selected and divided into the reference group and the research group. The reference group was treated by modified gastric tube placement, and the research group was given the Rehabilitation New Liquid Spray intervention. The effect of the interventions on two groups was observed. Results: The incidence of nasal mucosal injury in the research group was lower than that in the reference group, and the incidence of pharyngeal mucosal injury in the research group was lower than that in the reference group (P < 0.05). The pain score of the study group was lower than that of the reference group at 8 h, 12 h and 24 h after replacement, and the incidence of hoarseness, swallowing discomfort and dry oropharynx was lower than that of the reference group (P < 0.05). Conclusion: The application of modified gastric tube placement and Rehabilitation New Liquid Spray intervention in patients with indwelling gastric tube can effectively reduce the nasopharyngeal injury and improve the pain of catheterization.
