Numerical simulation and experimental study of influence of ventilation on temperature distribution in long and narrow space;

For the long and narrow space at non-normal temperature,it is difficult to lower the temperature to a satisfied degree only by ventilation,but as an assistant method,the fine mist would be effective.

In the case of long and narrow space where a great deal of heat producing, it is feasible to use fine mist as an assistant means to lower the temperature.

Preliminary study on engineering method to predict smoke movement in long-narrow confined spaces;

An experimental investigation was conducted of the intensified boiling heat transfer of R 11 in the narrow spaces of a compact heat transfer tube bank consisting of rolled surfaces.

On the basis of our experimental observation an analysis of boiling heat transfer mechanism in narrow space is developed and a model of boiling heat transfer is provided as fol-lows:There exists a eritical gap size(Bond=0.

The monolithic assembly and lifting of a large struct ural member were carried out on ground in narrow space,using fully the per formance of a hoist.

This paper used the temperature and strain characteristic of the optical fiber Bragg grating,designed and manufactured a set of fiber Bragg grating sensor for measuring temperature & gap in tiny surface.
