Development of reciprocating magnetic refrigerator.

Dynamic Simulation Model of a Reciprocating Compressor in a Refrigerator

In this paper, a set of mathematical model to be used for predicting the dynamics of a reciprocating compressor in a refrigerator has been developed. Based on the conservation of energy and mass, the model was established by dividing a global compressor into ten controlling volumes. The model was validated by the experimental results from literatures. It could be calculated for the transient ch...

A simple magnetic refrigerator evaluation model

The simple evaluation model utilizing the selective parameters for the preliminary analysis for magnetic refrigerator (MR) development is proposed in this paper. The magnetocaloric effect and the related magnetic field applied for MR are also discussed. The model and system analysis following the algorithm expressions and the material characteristics required for MR are arranged and derived in ...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
