The corrugation angle is known as the key variable that controls heat transfer enhancement and fouling resistance of a BPHE.
Summary of the Brazed-Plate Heat Exchangers (BPHEs) for this Fouling Study BPHE A1 BPHE A2 Dimensions, L * W 13.
This LMTD method does not consider either the degree of superheat or the degree of subcooling on the refrigerant side of the BPHE.
Resistance temperature detectors (RTDs) were used to read the water and refrigerant inlet and outlet temperatures while the refrigerant saturation temperature was obtained from the refrigerant pressure, for which the transducer was installed at the inlet of the BPHE.
During operation, the water becomes supersaturated near the heat transfer surfaces of the test BPHE.
The water flow rate is set by adjusting the metering valve at the outlet of pump 3, and the water entering temperature to the test BPHE is controlled by an electric heater immersed in the reservoir.
The pressure is taken at the inlet of the test BPHE while temperature sensors are installed before and after the test BPHE.
As summarized in Table 1, three BPHEs (A2, A3, and A4) had the same corrugation angle but different aspect ratios, while the fourth BPHE (A1) consisted of the same aspect ratio of A2 but with a different corrugation angle.
A common analysis method of single-phase heat transfer in BPHE is the modified Wilson plot technique.
The heat transfer coefficients for the hot and cold sides of the BPHE are thus obtained by:
Due to the similarity in geometries and configurations on the cold and hot channels of a BPHE, the flow regimes and the Reynolds number exponents on both sides can be assumed identical in certain ranges of Reynolds numbers.
