Experimental Investigation of Flow Regimes in An Operating Theatre of 1200-Beds Teaching Hospital
نویسنده
چکیده
Optimum design of air condition in surgical operating theatres requires more careful and refined control of flow and temperature characteristics to achieve sterile and comfort conditions. The present work is devoted to analyze the performance of HVAC system design in practical operating theatre in 1200-beds of Egyptian modern teaching hospital. The present experimental program comprises field measurements of air velocity, and temperature, in the vicinity of supply air diffusers and operating area. The obtained experimental results illustrate the distinct interaction of the HVAC system design parameters. The present work introduced some recommendations to ensure prevailing aseptic conditions and also demonstrated the effect of air conditioning system design on the temperature distribution the operating theatres.

Background: Operation theatre in a hospital requires considerable human and physical resources to deliver surgery services on an agreed schedule. However, operation theatres are sometimes underutilized due to avoidable last minute cancellations of operations. Cancellation of operations on the day of intended surgery results in operation theatre planning difficulties, hospital inefficiency and r...

Introduction Over the last fifty years gas-solids fluidized beds have played a very important role in many areas in the process industry, especially in chemical and petroleum industries. The existence of different flow regimes in fluidized beds at different operating conditions has been known for a long time and numerous studies have been carried out to define the flow regimes [1-6]. It is well...

متن کاملNumerical investigation of upward air-water annular, slug and bubbly flow regimes
In this paper, numerical investigation of upward two phase flow of air-water has been studied. Different conditions of flow regimes including annular, wispy annular, slug, churn and bubbly are simulated based on Hewitt and Roberts map, and a good agreement between the experimental data of the map and the numerical simulation has been observed. Accordingly, a proper CFD model in CFD software of ...
