    irreversibility analysis
    Opis:
    Irreversibility analysis was investigated by using refrigerants R22, R407A, and R407C in window type air conditioner system. The experimental study was conducted at various ambient temperatures and air volumetric flow rates to determine the parameters that cause the energy degradation of the system. The irreversibility was compared with respect to volumetric flow rates of the air passing through evaporator (14.15, 12.74, and 10.618 m3 /min) and different ambient temperatures (ranging from 28°C to 39°C dry bulb. Results show that the total irreversibility increases with refrigerant mass flow rate and ambient temperature for the three refrigerants. Additionally, R22 shows the highest irreversibility in low ambient temperature (28°C to 30°C) while R407A shows the lowest one with ambient temperature ranging from 30°C to 36°C. Both tested refrigerants are very good replacement for R22 in terms of irreversibility and energy analysis and these results are more remarkable with R407A.

    Opis:
    Jan Łukasiewicz, a prominent Polish logician and philosopher, dealt with the scientific analysis of the concept of cause using logic. He wanted first and foremost to construct a definition, which reconciles the irreversibility of causal relationship to the exclusion of time sequence. In this article, I show that his attempts led to many contradictions, paradoxes and inconsistencies between Łukasiewicz’s definitions and commonly recognized examples of causality, even those given by the author himself. First, I present the semantic and formal aspects of the definition proposed by him, and then I analyze examples, most of them proposed by the author. The main charges against his concept of causality are: the ambiguity of the concept of necessity; exclusion “for reasons of terminological” some causal phenomena from the range specified by the definition; paradoxes such as: the existence of the world is the cause of the existence of God; baseless demand, different subjects, and different features for cause and effect; disregard of the defnitive difference between post hoc and propter hoc; unjustified requirement of affirmative statements expressing a possession of attributes. The critique presented in this article is incomplete, but its function is to indicate both the value of logical analysis of philosophical concepts, and the dificulties of which such an analysis can entangle. Such an analysis can sometimes complete the process of defining certain concepts, but more often it provides an opportunity for further discussion and a better overall understanding.

    Opis:
    This paper presents mathematical modelling and numerical analysis to evaluate entropy generation analysis (EGA) by considering pressure drop and second law efficiency based on thermodynamics for forced convection heat transfer in rectangular duct of a solar air heater with wire as artificial roughness in the form of arc shape geometry on the absorber plate. The investigation includes evaluations of entropy generation, entropy generation number, Bejan number and irreversibilities of roughened as well as smooth absorber plate solar air heaters to compare the relative performances. Furthermore, effects of various roughness parameters and operating parameters on entropy generation have also been investigated. Entropy generation and irreversibilities (exergy destroyed) has its minimum value at relative roughness height of 0.0422 and relative angle of attack of 0.33, which leads to the maximum exergetic efficiency. Entropy generation and exergy based analyses can be adopted for the evaluation of the overall performance of solar air heaters.
