TWO PHASE CFD FLOW ANALYSIS OF R134a AND R1234yf REFRIGERANTS AND ITS EFFECT ON COOLING PERFORMANCE IN AN AUTOMOBILE HVAC EVAPORATOR CORE
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2017, Vol 13, Issue 10
Abstract
The purpose of this research is to conduct a two-phase fluid analysis and simulation for examining the influence of refrigerant (R134a/R1234yf) properties on cooling performance of an automobile HVAC (Heating, Ventilation and Air Conditioning) evaporator core and compare their performances. In this research, streamline deviation, static pressure, velocity magnitude, pressure co-efficiency, Reynolds number and turbulent kinetic energy play a key role in the comparison of the refrigerants R1234yf and R134a two-phase fluids. Subsequently, it was found that R134a properties were better towards the cooling performance of an automobile HVAC evaporator core.

SYNTHESIS OF CHALCONES VIA CLAISEN–SCHMIDT CONDENSATION REACTION CATALYZED BY SILICA-H2SO4 UNDER ULTRASOUND IRRADIATION
The synthesis of 1,3-diaryl-2-propenones was carried out by using ultrasonic irradiation in the presence of silica-H2SO4, which was used as a catalyst in solvent-free conditions. The advantages of this process are the hi...
Corrosion inhibition studies and Solvation Analysis of Pyridine N-oxides by Polarizable Continuum Model method
Solvation analysis and corrosion inhibition studies has been carried out for pyridine N oxide, 3-carboxypyridine N-oxide and 2-methylpyridine N- oxide in polar and nonpolar solvents having a wide range of dielectric cons...
Far from Equilibrium Maximal Principle Leading to Matter Self-Organization
In this work an extremal principle driving the far from equilibrium evolution of a system of structureless particles is derived by using the stochastic quantum hydrodynamic analogy. For a classical phase (i.e., the quant...
Molecular Interaction Studies in Ternary Liquid Mixtures of Quinoline at Varying Temperatures
