Bundle Diameter refers to the diameter of the tube bundle within the heat exchanger. For two tube pass triangular pitch configuration, it represents the overall diameter of the tube arrangement that forms the heat transfer surface inside the heat exchanger.
The calculator uses the formula:
Where:
Explanation: This formula calculates the bundle diameter based on the pipe outer diameter and the number of tubes arranged in a two-pass triangular pitch configuration.
Details: Accurate bundle diameter calculation is crucial for heat exchanger design, space optimization, flow distribution analysis, and ensuring proper heat transfer efficiency in thermal systems.
Tips: Enter pipe outer diameter in meters and number of tubes. All values must be valid (diameter > 0, number of tubes ≥ 1).
Q1: What is triangular pitch arrangement?
A: Triangular pitch is a tube arrangement pattern where tubes are positioned at the vertices of equilateral triangles, providing compact layout and efficient heat transfer.
Q2: Why is bundle diameter important in heat exchanger design?
A: Bundle diameter determines the overall size of the heat exchanger, affects fluid flow patterns, influences heat transfer efficiency, and impacts pressure drop characteristics.
Q3: How does two tube pass configuration differ from single pass?
A: In two tube pass configuration, the fluid passes through the tube side twice, typically using a U-bend or return header, which affects flow distribution and heat transfer characteristics.
Q4: What factors influence the choice of tube arrangement?
A: Factors include heat transfer requirements, pressure drop limitations, fouling tendencies, maintenance accessibility, and space constraints.
Q5: Are there limitations to this calculation method?
A: This empirical formula provides approximate results and may need adjustment for specific applications, extreme conditions, or non-standard tube layouts.
