Downstream Development

Results of the experimental studies of the subsonic round and plane both the macro and micro-jets are reported. The new phenomenon associated with transformation of the round micro-jets into the plane micro-jets under effect of a transversal acoustic field is revealed. It is shown, that its downstream development is determined by the sinusoidal instability mechanism of the plane jet. The disintegration phenomenon of the micro-jets on two jets developing separately from each other is revealed. It is found, that two new micro-jets are spreaded under a definite angle to each other and subjected by high-frequency secondary instability. It is shown, that sinusoidal instability of a plane jet is saved for macro and microjets both with acoustic and without acoustic effect. It is found, that the pseudo plane micro-jet at the presence of an acoustic field demonstrates presence in it of the vortex structures and dependence of the jet splitting angle from the frequency acoustic. The new phenomenon, so-called twist of a plane of a micro-jet on its edges in direction of the stream velocity vector created by a transversal acoustic field is revealed. It is shown, that process of the micro-jet twist result in a stupor of the jet downstream development and delay of its turbulisation. It is found, that sinusoidal instability of the round microjet depends on a direction of the acoustic field vector while the plane micro-jet does not depend. It is shown, that the new phenomena detected during investigations of a development both the round and plane micro-jet are stipulated by commensurability of the transversal acoustic field energy with the micro-jets energy.

Dust Precipitation

In order to reduce the total dust discharge from high-temperature furnaces, this study advocates the use of the energy of the acoustic field formed in the furnace body with application of acoustic generators of Hartmann whistle type. The paper provides theoretical justification of dust precipitation inside the furnace and develops principles of its implementation. The efficiency of this method is shown by examples of industrial implementation. Keywords: dust precipitation inside the furnace, acoustic field energy, Hartmann whistle

Ch Selection

In Wireless Sensor Networks (WSN) the energy of Sensor nodes is not certainly sufficient. In order to optimize the endurance of WSN, it is essential to minimize the utilization of energy. Head of group or Cluster Head (CH) is an eminent method to develop the endurance of WSN that aggregates the WSN with higher energy. CH for intra-cluster and inter-cluster communication becomes dependent. For complete, in WSN, the Energy level of CH extends its life of cluster. While evolving cluster algorithms, the complicated job is to identify the energy utilization amount of heterogeneous WSNs. Based on Chaotic Firefly Algorithm CH (CFACH) selection, the formulated work is named “Novel Distributed Entropy Energy-Efficient Clustering Algorithm”, in short, DEEEC for HWSNs. The formulated DEEEC Algorithm, which is a CH, has two main stages. In the first stage, the identification of temporary CHs along with its entropy value is found using the correlative measure of residual and original energy. Along with this, in the clustering algorithm, the rotating epoch and its entropy value must be predicted automatically by its sensor nodes. In the second stage, if any member in the cluster having larger residual energy, shall modify the temporary CHs in the direction of the deciding set. The target of the nodes with large energy has the probability to be CHs which is determined by the above two stages meant for CH selection. The MATLAB is required to simulate the DEEEC Algorithm. The simulated results of the formulated DEEEC Algorithm produce good results with respect to the energy and increased lifetime when it is correlated with the current traditional clustering protocols being used in the Heterogeneous WSNs.

Waste Energy

This work covers waste energy utilization of the combined power cycle by using it in the candle raw material (paraffin) melting process and an economic study for this process. After a partial utilization of the burned fuel energy in a real bottoming steam power generation, the exhaust gas contains 0.033 of the initially burned energy. This tail energy with about 128 ºC is partly driven in the heat exchanger of the paraffin melting system. Ansys-Fluent Software was used to study the paraffin wax melting process by using a layered system that utilizes an increased interface area between the heat transfer fluid (HTF) and the phase change material (PCM) to improve the paraffin melting process. The results indicate that using 47.35 kg/s, which is 5% of the entire exhaust gas (881.33 kg/s) from the exit of the combined power cycle, would be enough for producing 1100 tons per month, which corresponds to the production quantity by real candle's factories. Also, 63% of the LPG cost will be saved, and the payback period of the melting system is 2.4 years. Moreover, as the exhaust gas temperature increases, the consumed power and the payback period will decrease.
