Pipe Cooling

A nested class within the HoH (Heat of Hydration) module used to define pipe cooling properties and assign them to specific nodes for reducing hydration temperatures in concrete structures.

Constructor

HoH.PipeCooling(name, pipe_diameter, convection_coeff, specific_heat, weight_density, inlet_temp, flow_rate, start_stage, end_stage, start_time, end_time, node_list, id = 0)

Parameters

  • name (str): Name of the pipe cooling group.
  • pipe_diameter (float): Cooling pipe diameter.
  • convection_coeff (float): Convection coefficient of the cooling pipe.
  • specific_heat (float): Specific heat of the cooling water.
  • weight_density (float): Density of the cooling water.
  • inlet_temp (float): Inlet temperature of the cooling water.
  • flow_rate (float): Flow rate of the cooling water.
  • start_stage (str): Starting construction stage for the application.
  • end_stage (str): Ending construction stage for disengagement.
  • start_time (float): Time of application (hr) relative to the start stage.
  • end_time (float): Time of disengagement (hr) relative to the end stage.
  • node_list (list[int]): List of node numbers defining the path of the pipe.
  • id (default=0): Optional ID for the pipe cooling group (auto-assigned if 0).

Object Attributes

  • NAME (str): The name of the pipe cooling group.
  • PIPE_DIAMETER (float): The diameter of the cooling pipe.
  • CONVECTION_COEFF (float): The convection coefficient.
  • SPECIFIC_HEAT (float): The specific heat capacity of the water.
  • WEIGHT_DENSITY (float): The weight density of the cooling water.
  • INLET_TEMP (float): The inlet temperature of the water.
  • FLOW_RATE (float): The flow rate of the cooling water.
  • START_STAGE (str): The construction stage where cooling begins.
  • END_STAGE (str): The construction stage where cooling ends.
  • START_TIME (float): The start time (hr) relative to the start stage.
  • END_TIME (float): The end time (hr) relative to the end stage.
  • NODE_LIST (list[int]): The list of nodes outlining the pipe path.
  • ID (int): The ID of the pipe cooling entry.

Methods

json

Generates the properly formatted JSON payload for MidasAPI.

pc1 = HoH.PipeCooling("PC1", 3, 133.7, 4186, 0.001, 15, 20, "CS1", "CS1", 10, 100, [2809, 2810])
print(HoH.PipeCooling.json())

create

Sends the PUT request to create all stored PipeCooling objects in Civil NX.

HoH.PipeCooling.create()

get

Retrieves the PipeCooling configuration from Civil NX.

print(HoH.PipeCooling.get())

sync

Fetches data from Civil NX and reconstructs the local class instances.

HoH.PipeCooling.sync()

delete

Deletes all pipe cooling objects from both Python and Civil NX.

HoH.PipeCooling.delete()

clear

Clears all locally stored PipeCooling objects without affecting the Civil NX database.

HoH.PipeCooling.clear()
