The phenomenon of steam–water direct contact condensation has significance in a wide range industrial applications. Superheated steam was injected upward into cylindrical water vessel. Visual observations were conducted on turbulent jet to determine the dimensionless length compared nozzle exit diameter and maximum swelling ratio as function mass flux at exit, with gas ranging from 295–883 kg/m...

By establishing a mathematical model to simulate mixed jet of oxygen and superheated steam from coherent supersonic lance, we studied the effect on fluid characteristics jet. The was initially verified through laboratory experiments prior analyzing in detail. These included velocity, temperature, turbulent kinetic energy (TKE), mass distribution. results showed that, at an ambient temperature 1...

A comparative analysis of the methods approximate thermal calculation superheated steam condenser compression heat pump supply system is presented. The working substance and condensing refrigerant R410a. When single-zone method applied, calculated by one area with inclusion overheating in condensation use coefficient. two-zone assumes two separate areas, viz. cooling its actual condensation. ap...

Wood drying is essential for preparation of this natural resource for practical applications. Solar drying can reduce drying costs and energy consumption. There are many potential models to describe the drying process. However, most models confirm that the tortuosity of the moisture transport path is an important control parameter during the diffusion-controlled drying process. Microwave heatin...

In Central Europe the main species that are used for the production of sawn wood are spruce, pine, and European beech. After the sawing process, the sawn timber is technically dried to a certain moisture content by means of condensation drying. The water movement in the cellular structure, which is caused by the drying process, draws some of the extractives into solution. In the process of kiln...

The temperature of exhaust gases from simple cycle gas turbine generation sets (GENSETs) is usually very high (around 500 C), and a heat recovery steam generator (HRSG) is often used to recover the energy from the exhaust gases and generate steam. The generated steams can be either used for many useful processes (heating, drying, separation etc.) or used back in the power generation system for ...
